Why do phones explode (and how to prevent it)

The Galaxy Note explosion incidents are a nightmare to Samsung as well as the smartphone users. While this is the first time everyone caught battery ignitions at a global level, it is one of the infamous accidents associated with smartphones. There are numerous incidents of smartphones catching fire every now and then causing harm to users. They usually catch fire while charging but there are incidents that prove otherwise as well. “Explosion” is quite a dramatic term for smartphones catching fire, but people usually relate it to these incidents. Today, let’s see why do smartphones explode and how we can prevent it.

So, Can batteries really explode?

Why do phones explode (and how to prevent it)

The smartphones batteries are basically Lithium batteries, both Li-ion and Li-Po batteries. They contain inflammable materials which can make your smartphone go haywire if reacted violently. The Lithium batteries operate on the basic principle of Cathode-Anode which you might have studied in Physics 101 class. The cathode reduces and releases electrons while the Anode oxidizes and collects electors. The transfer of electrons between the Cathode and Anode generates current.

The cathode and Anode are separated by a small membrane/valve that protects them from reacting violently. So, if the membrane collapses making cathode and anode to contact, then everything goes south. They both chemically react leading to a violent combustion which is quite rapid. But smartphone batteries doesn’t have enough chemicals to really explode in a larger scale. However, things can go worse if the smartphone is encased in a really tight case. The case can build up pressure due to combustion which can lead to a powerful outburst which can cause severe damage to the users carrying it.

So, the batteries don’t really explode, they combust quite rapidly. But if you’re encasing your smartphone while charging or in hot conditions, things can get real nasty.

Who is the Culprit? Manufacturer or User?

It is quite a tough question to answer as no one can be blamed completely in such situations. Manufacturers usually implement a fail-safe circuit to prevent phone from overheating while charging or performing intensive tasks. It prevents the device from getting too hot for them to explode. A quality hardware and circuit components would definitely prevent such accidents. In the case of Note 7 incident, Samsung has cleared that a batch of devices has battery defects which caused the explosions but this is just a rare event. Usually, only a hand full of devices caught on fire from the millions sold.

Smartphone usage habits contribute a lot to such unfortunate events. Most of the users simply ignore many safety precautions considering them irrelevant in real time. Using smartphone while charging, placing phones in hot areas, usage of damaged chargers and wall ports can also contribute to explosions. So, let your smartphone take some air while it’s charging. Don’t push the boundaries too far that you regret it later. Moreover, it doesn’t even take a full hour for the smartphones to charge 70-80% these days. So, better sit the hour in the real world while your precious smartphone is gaining some juice.

Why do phones explode (and how to prevent it)

Always purchase a smartphone with good build quality to make sure the device has quality components. It really burns down to trust and loyalty of the users towards the manufacturers. The other important factor is your smartphone usage habits which can prove fatal at times. So, check down the below preventive measures you can take for your safety and that of your smartphone.

Protect yourself from Battery Explosions

If it’s a hardware defect, we can’t do much but we can surely protect ourselves by following some safety precautions. Check the below tips that protect you and your device from catastrophes.

  • Look out for danger: You can sense the warning signs in advance that your battery is damaged. Look out for popping sounds, hissing, or swelling of the battery. If you observe something like this, take the device to the service center and get the battery replaced.
  • Don’t Charge When the device is too hot: If you observe that your device is getting too hot while charging, pull the plug out. Allow your device to cool down before charging it again. If it happens repeatedly, better take it to authorized service center.
  • Always use Company chargers: Always use the charger included in the box to make sure your device is being charged properly. It should receive optimum voltage and current and should not exceed it. Don’t use 3rd party chargers if you’re not sure it’s compatible with your device or not.
  • Make sure the source is safe: Avoid charging your device from damaged wall ports and power extensions. It could damage your device severely.
  • Don’t use Phone while Charging: Ahh. This is the major cause of battery explosions and human casualties. The smartphones become too hot if you use it while charging, this may lead to an aggressive fire.
  • Remove Case while Charging: Remove the mobile case while charging as this will let the heat dissipate to the surroundings easily. So, your mobile won’t get hot while charging.
  • Don’t Charge it too long: Many of us have the habit of charging the device overnight or leaving your phone to the car dashboard for a long time. This could potentially overcharge the device and could lead to unfortunate incidents. Also, this will weaken your battery thus reducing battery life.
  • Don’t Charge near flammable objects: Don’t keep your device charging near a radiator, pillows or any flammable objects just to make sure things won’t go out of hand.

Conclusion

The smartphone batteries can be a potential danger if you let them. Only a tens of battery explosion incidents are reported out of millions of smartphones sold every year. But that doesn’t mean the danger is not real, you need to be alert and take preventive measure to avert any mishap.

If you find a battery swollen or damaged, take it to the retailer or service center and get it replaced. If you have device covered under warranty, you’ll get a replacement battery for free. Never throw the damaged battery in open places or trash and it could lead to fire hazards.

Finally, back to the initial question. Do batteries explode and are we in danger? No. But that doesn’t mean that the threat is not real. It can get as real as it could be. So, play safe and avoid any smartphone accidents.

Why do phones explode (and how to prevent it)

Every now and again we hear unfortunate stories about gadget batteries catching fire and even exploding (a term that is often used even for incidents that are less dramatic), sometimes causing harm to the unsuspecting user. While very rare, Samsung has been forced to recall its latest Galaxy Note 7 smartphones after concerns were raised that a small number of its handsets are shipping with defective batteries that may explode. Once again, dangerous lithium-ion batteries are back in the spotlight, but what actually causes a battery to go haywire?

Why do phones explode (and how to prevent it)

Causing explosions

Lithium-ion batteries seldom bulge or explode, but when they do, there are two leading causes. The first is a puncture, which might be caused by dropping your phone. A break in the thin compacted battery material between cells can produce to an internal short circuit, leading to swelling and potential explosions. Alternatively, cheaper batteries can sometimes accidentally feature rare microscopic metal particles inside that might come into contact with other parts of the battery cell, also leading to a short circuit.

With the Galaxy Note 7, Samsung and various reports suggest that the issue is caused when the device is charging, which leads us to our second major cause – heat. Excessive heat can again cause again internal short circuit within the battery, by breaking down the internal cells. However, this only usually occurs at very high temperatures, unless the battery is faulty. Overcharging may also be an issue, which is caused by batteries receiving more current than they can safely handle, causing them to overheat.

Too much heat in one area of the battery can lead to “thermal runaway”. This happens when an area of a battery can’t cool down quickly enough, resulting in a breakdown chain reaction that generates more and more heat. In other words, excess heat causes a reaction that accelerates the temperature increase. Eventually, this can lead to a fire or explosion.

Typically, high-quality batteries will include safety features that can usually prevent this dangerous reaction from taking place. However, Samsung has stated that it has purchased battery packs from multiple providers, and perhaps some of these are more prone to failure than others.

Charging and heat

There are a number of potential causes of excessive heat in and around the battery in a modern smartphone. The move towards fast charging technologies is now forcing additional current into lithium-ion batteries, and with every power transfer there is always some heat generation. The more power, the higher the potential heat. While some of this heat-loss will occur at the battery itself, some heat will also be lost in the fast charging power conversion and power management circuitry, which is usually located next to the battery. This could certainly cause more heat at one end of the battery than the other.

The processors inside today’s smartphones are also producing more heat than the handsets from 3 or 4 generations ago. While not usually nestled next to a battery, this could further add to the temperate inside a modern smartphone, making it more difficult for heat to transfer away from the battery area.

We should be clear though that Samsung has indicated that it is the batteries that are at fault in the Galaxy Note 7 and not any other part of the handset. It seems unlikely that the Galaxy Note 7 has be built in such a way that it is producing too much heat that makes it unsafe to stick a battery inside. Instead, it’s more likely that just a small percentage of the batteries that Samsung has purchased are not coping properly with the heat produced or current provided while charging. Either by not matching up to the required charging specifications or by simply coming from a faulty batch.

Protecting yourself

Without knowing exactly what is causing issues with Samsung’s Galaxy Note 7, we can’t say precisely how to avoid potential problems. However, there are some general tips to follow that can help protect yourself and your device from catastrophe. General warning signs that your battery is damaged and could explode include a hissing sound, popping, or swelling.

  • Stop charging your phone it if becomes too hot. Allow your phone to cool down before charging it again and make sure that you don’t cover your phone to let heat escape properly.
  • Stick to first-party chargers. Use the charger included in the box to make sure that your phone is receiving the optimal voltage and current. If you’re using a phone with a USB Type-C port or Quick Charge, it might be wise to stick with the cable that came in the box too.
  • Don’t charge your phone in bed. I know it’s very tempting to watch a video or read before you fall asleep, but you don’t want to roll over on your phone and have it overheat. Not to mention that leaving your phone under a pillow while it charges will cause it to heat up.
  • Be mindful of where you charge your phone. Avoid charging for long periods of time in really hot places, such leaving your phone on a car dashboard, next to a radiator, or in direct sunlight on hot days.

If you do happen to notice your battery swelling, unplug your phone and remove the battery, but only if the battery is user removable. Don’t attempt to dispose of the battery or device in the trash. Always get rid of your batteries at authorised disposal facilities or some electronics retailers, such as Best Buy, that offer battery recycling services.

If your battery and/or device is damaged as a result of a swollen or exploded battery, take your device to the retailer that you purchased it from or get in contact with the manufacturer. A replacement battery or device will usually be issued, especially if you have a warranty.

We Give You the Reasons Why Devices Explode So You Can Protect Yourself

Why do phones explode (and how to prevent it)

Just recently, Samsung enforced a total pull out of the Galaxy Note 7 worldwide due to issues with the battery pack. Reports said that some units actually exploded upon charging. As drastic as it sounds, it really did and could happen with anyone. With this, then why do smartphones explode? And what can we do to prevent it from happening?

What Might Cause for Your Device to Explode?

As history of tech products has already taught us, product recalls are totally normal if it entails added safety and security for the users. Mobile phones have long been using battery packs made of lithium-ion. These battery packs are some of the most stable power sources currently in the market, so they rarely react explosively. However, there are two main reasons that may cause this.

The first reason is leaking. Dropping the device, along with the battery inside of course, may cause a tear in the battery material which can induce internal short circuit. This may lead to swelling and eventually lead to explosion. On the other hand, cheap batteries provided either by the official manufacturer or third-party vendors may inadvertently pack microscopic metal particles. These might make contact with other battery cell parts, which again may lead to internal short circuit.

The second major reason is heat production. It is common knowledge that charging devices produce heat in the process. However, if a product does not have a proper heat management system or if it is faulty, internal short circuits may again occur. Do take note that certain amounts of heat are normal, as energy transfer takes place while charging. Be wary though of above normal temperatures while plugged in.

Overcharging the device might also cause this, as batteries receive more current than they can handle. A majority of modern mobile phones now have safety features to prevent this, but some faulty devices might have been missed. A lot more technical processes go into this discussion, but that’s the general idea of why and how battery packs explode.

What Can You Do?

Here are some safety measures of what you can do to prevent battery pack explosions from occurring.

Stick to Manufacturer Chargers
The original chargers provided by the device manufacturer always come with safety precautions. They are fully optimized to work together with that particular device and model. The voltage, current, and overall performance of all components have been scientifically measured to certain safety standards. This is especially true when using quick charging features.

Don’t Let the Device Be Too Hot
As mentioned above, a certain amount of heat would be acceptable for charging devices. However, when the phone becomes too hot for comfort, then it is usually a sign for you to unplug it. Also make sure that the back of the phone is not covered entirely to allow for proper heat dissipation.

Don’t Overcharge the Device
Some users have the habit of leaving their phones plugged in at night as they sleep. While it is true that most devices already have safety precautions and are smart enough to stop juicing up when already full, the battery still has the tendency to gain more power than it can handle. Also, putting the device on the bed or under the pillow may cause it to overheat, even if unplugged.

Charge Your Device in Safe Places
We must look at a safe place for charging the device, meaning that it must not also present hazardous elements. Avoid plugging in near extremely hot places, and also where direct sunlight is abundant. Also check for wet areas as even waterproof phones usually don’t have waterproof chargers. Also avoid placing the phone near edges where it might easily slip. Remember, the leading causes of battery explosions are battery leaks due to falls and overheating.

Why do phones explode (and how to prevent it)

Smartphones are cool. Explosions are cool. But combining the two are not so cool. Every now and again we hear cases of smartphones exploding, and this has become a major concern because such explosions are life-threatening. While it’s very rare, Samsung was forced to recall the entire Note 7 lineup after over thirty-five cases of smartphone explosions were reported.

Since the Note 7 fiasco, we’ve had several isolated cases of smartphones exploding, and last year we witnessed the worst case scenario where a man died after his phone exploded and caught fire. To help you protect yourself, we’re going to cover the main reasons smartphones explode and explain what you should do to stay safe.

What Causes Smartphone Batteries to Explode?

While manufacturing defects are the main reason smartphones explode, there are also situations on the user’s end that could cause a battery to explode. Here are the main reasons why smartphone batteries explode.

1. Manufacturing Defects

A bad batch of batteries (as was the issue with the Note 7), use of a wrong component, or a fault in the assembly line that caused a component to be damaged can cause a battery to malfunction. When this happens, an explosion is hard to avoid.

Why do phones explode (and how to prevent it)

Flawed design and counterfeit products are also major causes of battery failures and explosions. You’re likely to see this in cheap products or from manufacturers who are clearly cutting corners. Many of the cheap and counterfeit products do not contain the required safety features offered by reputable brands.

2. Inside Fracture

An inside fracture, which might be caused by dropping your phone, can cause your phone battery to swell and eventually explode. A hard fall can cause the thin compacted battery material that separates the cells to break, and this can produce an internal short circuit leading to swelling and potential explosions.

In the event of a drop, most people will run to the nearby repair center to have their screen repaired. While the key focus is usually on the screen, many people undermine the impact the fall could have had on the battery. What many don’t know is that a fall can also alter the chemical and mechanical structure of the battery. Such changes can cause the fail-safe circuitry to fail, paving the way for internal stress which could lead to swelling and potential explosions.

To be on the safe side, it’s good to always check your battery’s health regularly, especially if your phone has hit the floor several times. Here are the signs to look for:

  • Deformation
  • Swelling
  • Excess heat generation, especially when charging
  • Phone restarting on its own
  • Battery draining easily
  • Phone not charging after being plugged in

If you see any of the above signs, you should consider replacing your phone’s battery. Paying close attention to these symptoms can help to avoid battery explosions.

3. Excessive Heat

Excessive heat can break down internal cells within the battery, and this can also cause an internal short circuit. However, this can only occur in extremely high temperatures, unless the battery is damaged. Excessive heat can result from overcharging since the battery will be receiving more current than it can safely handle, causing it to overheat.

Why do phones explode (and how to prevent it)

If the excess heat builds up inside the battery, it causes a reaction known as a “thermal runaway.” This refers to a situation where an increase in temperature changes the chemical reactions in a way that causes a further increase in temperature. In other words, rather than helping the battery to cool down, thermal runaway accelerates temperature increase — a catalyst for explosions.

There are many factors that can cause your phone to naturally heat up, such as playing graphics-intensive games. While your phone can handle all these functions just fine, performing them in a hot environment could impact your battery negatively. For example, playing music for long hours in direct sunlight can make an already straining phone struggle to cool itself.

4. Using the Wrong Charger

The use of a wrong or faulty charger can cause an explosion as the charger might supply more current than what your battery can handle. Also, manufacturers of cheap chargers often don’t meet the safety specifications required by USB devices. Such chargers often use sub-standard quality materials or incorrect gauge of wire that lack the required overcurrent protection.

How to Protect Yourself

Now that you know why smartphone batteries explode, there are measures you can take to protect yourself and your devices from explosions. By following these simple tips, you’ll be able to eliminate all the common causes of smartphone explosions.

  • Don’t charge your phone in bed – We know how tempting it can be to charge your phone while watching a video in bed. However, this is very risky, as you can easily roll over your phone and have it overheat.
  • Stick to first-party chargers – If possible, use only the charger that comes with the phone. This ensures your phone is getting the optimal voltage and current.
  • Buy your devices from reputable retailers – Today, the online stores are flooded with cloned products, and it might be hard to distinguish the real ones from counterfeits. Buying from manufacturers ensures you get high-quality products that are free from manufacturing defects.
  • Always allow your phone to cool down – If it gets hot during charging, unplug it to allow it to cool down. Avoid using it or keeping it in hot environments.
  • If a device is recalled, make sure to return it. The sooner the better.

Wrapping Up

While smartphone explosions are a real thing, these occurrences are rare, and manufacturers have taken huge steps to ensure smartphones’ safety. For example, after the Note 7 debacle, Samsung implemented an eight-step battery test to prevent future phones from exploding. For your safety, it’s good to ensure you’re buying known brand names and from reputable outlets.

There can be numerous causes for the phones to heat up and explode, which cant be predicted, but certainly can be avoided. Following are the reasons why smartphones explode and how it can be avoided.

Why do smartphones explode and how to avoid and control heating

Despite new technology and improved smartphones every year, the batteries tend to catch fire and even explode that even ends up harming the unsuspected user. Samsung has been one of the companies that had few of its handsets shipped with defective batteries. So, are the lithium-ion batteries to be blamed or is it something else that causes the battery to go haywire, let’s find out.

Reason of smartphones to explode

Every phone uses a lithium-ion battery that seldom bugles or even explodes, but there are two reasons as to what could cause this. The first reason could be due to puncture that happens because of the phone dropping or a break in the thin compact battery that can lead to short circuit and even explosion. There are also times when cheap alternate batteries sometimes feature rare microscopic metal particles that viably come in contact with other parts of the battery cell, which lead to short circuit.

There have been many reports of the smartphones bursting while charging. This happens because of excessive heat that is that can lead to a short circuit within the battery that breaks down the internal cells. This majorly happens at very high temperatures with a faulty battery. Many a time, overcharging can cause this problem as batteries start receiving more current than what they can handle that leads to overheating.

A lot of heat in just one area of the battery leads to thermal runaway, which happens after the battery can’t cool down quick enough that results in a breakdown chain reaction that eventually leads to fire.

Causes of excessive heat while charging

There are numerous reasons as to why excessive heating is caused in and around the battery. Phones these days come with fast charging that tends to force additional current into the lithium-ion batteries that cause heat generation.

Even the processors used in the phones produce more heat than the handset that also to an extent adds to the temperature, which makes it difficult for heat to transfer.

Tips on how to protect yourself from smartphone explosion

There can be numerous causes for the phones to heat up and explode, which cant be predicted, but can certainly be avoided. Following tips can help you in such cases.

Use the original charger- While charging the phone, use only the first party charger that comes in the box.

Stop charging if the phone gets too hot- Make sure your phone is cool before you charge it, or wait for it to cool down before you plug it in the charger.

Try not to charge the phone near the bed- It actually is the most preferable way for one to charge the phone, but there are times when we keep the phone under the pillow for charging. This causes the phone to heat.

Don’t charge the phone for too long- Try avoiding your phone for too long, especially in hot places like the car or the close to the radiator or direct sunlight, during hot days.

Smartphone batteries explode and there are several reasons behind it.

One cannot talk about exploding batteries without referring to the ill-fated Samsung Galaxy Note 7. As much as we hate seeing a smartphone like the Galaxy Note 7, arguably one of the best smartphones Samsung has ever produced with loads of power and quite a few unique features, we have to accept the battery issues and move forward.

Why do phones explode (and how to prevent it)

However, Note 7 is not the only smartphone to have gone through such issues. It happened with Nokia in 2007, and we are pretty much sure it may occur in the future again because smartphone vendors are extensively focusing on delivering slimmer devices by compromising on design aspects, which is the case with the Galaxy Note 7.

But is this the only factor or are there any other factors that lead to the explosion of batteries in smartphones? Let’s find out.

Before we do that, let’s get to know how the batteries in smartphones work in the first place.

Note: Given the fact that most smartphones use Li-ion batteries, we will mostly focus on explaining how Li-ion batteries work.

Li-ion battery and its working

As with the case of most batteries, the Li-ion batteries consists of three parts – the cathode, the anode, and the electrolyte.

The anode (holds negatively charged ions) and cathode (holds positively charged ions) are nothing but electrical terminals located on either side of the battery. These are called electrodes, and the chemical between these electrodes is called electrolyte, which helps conduct electricity. Both the cathode and anode are in the electrolyte but are separated by a physical barrier to restrict them from touching each other.

The cathode pushes positive charge through the electrolyte towards anode which after attracting it, sends power to different components of the phone, which means discharging in other words. And the exact reverse of this process is nothing but charging – something which happens when you plug in the charger.

So, why do they explode

Well, after all, they are batteries and batteries degrade over time. That’s precisely the reason why a two-year-old smartphone doesn’t deliver the same battery life as a six-month-old smartphone does. Moreover, these batteries are highly temperature sensitive (have very low melting points – around 180-degree Celsius) and can explode mainly for two reasons: heat and physical damage.

Like mentioned earlier, the electrodes are separated by an electrolyte (usually a paste like substance) which is highly volatile. When this paste (full of superheated liquids filled with melted metals) ruptures out of a battery casing due to physical damage, it creates an explosion.

आगरा में दो युवक चार्जिंग में लगे फोन में इयरफोन लगाकर गाना सुन रहे थे. इसी दौरान उनका मोबाइल फोन गर्म हो गया, जिसके बाद उनका मोबाइल फोन ब्लास्ट कर गया. मोबाइल फटने के इस हादसे से एक युवक की मौत हो गई और दूसरा युवक गंभीर रूप से घायल हो गए. इस तरह की घटनाओं के बाद जो बड़े सवाल उठते है वो ये कि आखिर मोबाइल फोन ब्लास्ट क्यों होते हैं? मोबाइल में आग लगने जैसी घटनाएं क्यों होती है? आइए जानते हैं कि मोबाइल ब्लास्ट होने की बड़ी वजहें कौन-कौन सी है.

बैटरी की ओवरचार्जिंग

मोबाइल ओवर चार्जिंग की समस्या तब आती है जब बैटरी को कई घंटों तक चार्जिंग पर लगाकर छोड़ दिया जाता है. मोबाइल की बैटरी को जरूरत से ज्यादा चार्ज करना, मोबाइल की बैटरी के फटने की एक बड़ी वजह है. जब बैटरी को जरूरत से ज्यादा चार्ज किया जाता है तो कैथोड से एनोड पर जरूरत से ज्यादा लिथियम आयन पहुंच जाता है. जानकारों के मुताबिक अधिकतर मोबाइल की बैटरियों में ओवर चार्जिंग से बचाने की व्यवस्था की हुई होती है. फुल चार्ज होने पर बैटरी का अपने आप चार्ज होना बंद हो जाता है. लेकिन, हाल में हुए हादसों से पता चला है कि इस व्यवस्था में भी दिक्कतें पाई गई हैं. इसी लिए मोबाइल एक्सपर्ट्स कभी भी बैटरी को 100 फिसदी चार्ज न करने की सलाह देते हैं.

फास्ट चार्जिंग वाले चार्जर का उपयोग

पिछले कुछ समय से मोबाइल कंपनियां अपने स्मार्ट फोनों के लिए जल्दी चार्ज करने वाले चार्जर दे रही है, इससे ये होता है कि कम समय में ही बैटरी में ज्यादा एनर्जी स्टोर हो जाता है. इस फास्ट चार्जिंग वाली बैटरी से सेम कंपनी का मोबइल चार्ज करते हैं हैं तो ये दिक्कत नहीं आती है, लेकिन जब उस चार्जर से दूसरे मोबाइल को चार्ज करेंगे तो मोबाइल के फटने के चांसेज बढ़ जाते हैं. मोबाइल एक्सपर्ट्स फास्ट चार्जिंग की सुविधा को खतरनाक मानते हैं. उनके मुताबिक इस सुविधा से बैटरी में प्लेटिंग की दिक्कत आने लगती है. दोनों इलेक्ट्रोड जिसके अंतर्गत कैथोड और एनोड आते हैं, वो अंडे की क्रेट की तरह होते हैं. चार्जिंग को दौरान लिथियम आयन को अंडों की तरह एनोड की क्रेट में बने खांचों में व्यवस्थित होना होता है. लोकिन फास्ट चार्जिंग के दौरान ये आयन तेजी से और अधिक मात्रा में एनोड पर आते हैं जिससे ये एनोड की क्रेट के खांचों में सही से व्यवस्थित नहीं हो पाते. जिसकी वजह से बैटरी के अंदर शार्ट सर्किट जैसी समस्या पैदा होती है.

चार्जिंग के समय मोबाइल का उपयोग करना

मोबाइल एक्सपर्ट्स का कहना है कि जब आप चार्जिंग के समय फोन का इस्तेमाल करते हैं, तो मोबाइल और उसका बैटरी दोनों गर्म हो जाती है. दोनों के एक साथ गर्म होने के कारण इस गर्मी के ब्लास्ट में तब्दील होने के चांसेज रहते हैं. हमें इस बात का ख्याल रखना चाहिए कि जब मोबाइल चार्ज हो रहा होता है तब उसके ब्लास्ट होने के चांसेज सबसे ज्यादा होते हैं. इसलिए मोबाइल को चार्ज करते समय उसका इस्तेमाल करने से बचे.

खराब हो चुके बैटरी का उपयोग

कई बार लोग पुराने हो चुके या फूल चुके बैटरी का प्रयोग निरंतर करते रहते हैं या सस्ते दामों में मिलने वाले खराब क्वालिटी के बैटरी का इस्तेमाल करते, जोकि थोड़ी देर की चार्जिंग में ही मोबाइल को गर्म कर देता है. इस तरह के बैटरी सबसे ज्यादा फटते हैं.

मोबाइल फोन की बैटरी को ब्लास्ट होने से कैसे बचाएं

बैटरी को ब्लास्ट होने से बचने के लिए हमें कुछ सतर्कता बरतनी चाहिए. जैसे- ओरिजिनल चार्जर से ही बैटरी चार्ज किया जाना चाहिए. चार्जिंग के दौरान मोबाइल का उपयोग ना करें. फोन को ज्यादा गर्म जगहों पर ना रखें. मोबाइल की बैटरी को आवश्यकता से अधिक चार्ज ना करें. ऐसे ऐप्स को इंस्टॉल करने से बचें जो आपके फोन को गर्म या हैंग करता हो. फास्ट चार्जिंग वाले चार्जर ना खरीदें.

इन दिक्कतों से बचने के लिए भविष्य की तैयारी

मोबाइल कंपनियों भविष्य में बैटरी फटने की समस्या से बचने के लिए नए तरीकों पर काम कर रही हैं. इसके लिए वैज्ञानिक इलेक्ट्रोलाइट को रासायनिक पदार्थों से बनाना शुरू कर रहे हैं. इलेक्ट्रोलाइट को रासायनिक पदार्थों से बैटरी ज्यादा गर्मी को बर्दास्त कर सकेंगे. साथ ही अधिक तापमान पर दूसरे रासायनिक पदार्थों में रिएक्शन नहीं होगा.

The Science Behind Exploding Cell Phones

Why do phones explode (and how to prevent it)

Cell phones are now one of the basic needs of people. They have become a necessity. Almost all people now have their own cell phones. They know how to use them. However, many people might not yet be aware about the risk of explosion among cell phones.

Recently, Samsung recalled its Galaxy Note 7 due to several cases of explosion. Exploding cell phones are not only Samsung’s problem. There are many such cases happening with other brands of cell phones. This means explosion is not an isolated case of Samsung. There is indeed something behind such explosion that only science can explain.

Why Do Cell Phones Explode?

Most cell phone explosions did not come from cell phones themselves. Most of the time, the batteries are the culprit. The common cause of battery explosion is when it is recharged too much. This is what happened with the Galaxy Note 7 and other brands of cell phones. On the other hand, battery defects are the primary reason.

In a cell phone’s battery system, there are separators that prevent two electrodes from connecting with each other. When the separators don’t work properly, it is more likely that these two electrodes will touch one another, and this will cause explosion.

When two electrodes come into contact, the electrolytes directly receive all the energy that is supposed to stay in the battery. This is unusual as it is the electrodes on the side that should receive it. Electrolytes are unstable and very sensitive to heat. When there is too much heat, electrolytes react and cause other chemicals to produce gas, which elevates the existing level of heat. And every time such chemicals react more and more gas is produced thereby producing more heat. This condition leads to thermal runaway that causes fire.

Why Do Overcharging Cause Batteries to Explode?

Most cell phones use lithium-ion batteries. These batteries are designed to prevent or tolerate overcharging. They are created like a bucket in which the bucket will never break when you keep on pouring liquid into it. What will happen is that liquid will only overflow but will not break the bucket.

When batteries explode, the probable reason is factory defect. Some batteries do not explode even after overcharging it. However, there is a limit in everything. Princeton University materials scientist Dan Steingart says, “The battery is like a rubber band. When you’re charging the battery, you’re stretching the rubber band; when you’re using it, you’re releasing it. Just like a rubber band can break if you stretch it too much, putting too much energy into one side will ruin the battery.”

Overcharging is different from charging too much. What makes cell phone batteries explode is too much charging. Charging a battery too much causes plating. When plating occurs, lithium produces dendrites that can short out the battery any time especially when the level of heat is high.

Overcharging and battery defects usually simply ruin the normal working of the battery, when battery does not work properly, it simply diverts the power to electrolytes, which are not supposed to receive it as electrolytes cause explosion when reacting with other chemicals.

How to Prevent Battery Explosion?

Scientists are now studying and developing a certain type of electrolyte that does not easily cause explosion. This type of electrolyte is called ionic fluid. Ionic fluid is less susceptible to heat. It is stable and safe. It requires much more heat to make it explode or to cause explosion. This electrolyte can tolerate overcharging.

However, scientists are still working on the downside of using ionic fluid. The problem in using ionic fluid is that it can affect battery life. This is because heat delivers energy and power. Anything that reduces heat also reduces energy and life in the case of battery. On the other hand, anything that holds much energy for long is a potential bomb.

For now, cell phone manufacturers still have to make do with lithium-ion batteries while scientists are still developing safer and better alternatives. Meanwhile, users must take into account safety precautions to prevent cell phone batteries from exploding. As much as possible, overcharging must be avoided. Furthermore, users should be careful in using incompatible chargers. Most chargers that are incompatible with batteries can cause explosion, too.

Recent news about exploding cell phones should not make people panic because this problem can still be avoided with the proper use of cell phones and chargers. Most manufacturers provide instructions and safety precautions in the use of batteries and chargers. All must be done is to simply follow them until a much safer battery is introduced.
