Will a swollen phone battery explode?

What I want to emphasize is that electronic devices are generally very safe, and they are not dangerous goods that make you sleep and eat hard. Purchase well-known brand products from reputable sales channels, be careful not to misuse or damage equipment, and you may not encounter safety issues.

Due to poor sealing, the dissolution inside leaks, causing it to bulge. This type of battery should not be used anymore.

Although there will be no explosion (as the battery is packaged in aluminum profiles rather than metal shells).

But if the solution inside leaks out, it will damage the circuit board of the phone itself. It is recommended to replace the battery with a new one.

Will mobile phone batteries expand and explode?

I believe everyone has seen news on the internet about phone battery bulges, expansion, and even explosions. These news sounds frightening. Today, the editor will take you to learn about this knowledge.

The reasons for expansion vary among different types of batteries. In the era of smartphones, regardless of whether it is an all-in-one device or not, the batteries used in mobile phones on the market are mainly lithium-ion batteries and lithium-ion polymer batteries. Other batteries are either outdated and have been phased out, or they are in the conceptual stage and have not been widely used.

Before introducing the issue, let's first understand the differences between the two types of batteries. Polymer lithium-ion batteries use the same positive and negative electrode materials as liquid lithium-ion batteries. The positive electrode materials are divided into lithium cobalt oxide, lithium manganese oxide, ternary materials, and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. Their main difference lies in the difference in electrolytes. Liquid lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries use solid polymer electrolytes instead. Lithium has very active chemical properties and is easy to burn. When the battery is charged and discharged, the internal temperature of the battery continues to rise, and the gas generated during the activation process expands. The internal pressure of the battery increases, and the pressure reaches a certain level. If there are scars on the shell, it will rupture, causing expansion, leakage, ignition, and even explosion. Polymer lithium-ion batteries, due to their use of solid electrolytes, do not leak or explode, but only expand, making them safer.

Compared to lithium-ion batteries, polymer lithium batteries have higher safety and cost, but they still suffer from swelling and swelling, which is closely related to the user's usage habits.

The main reasons for the expansion of rechargeable batteries are as follows:

1. Poor or unprotected battery protection circuit: This situation often occurs in mobile phones with detachable batteries. Many users prefer to purchase relatively inexpensive non original batteries, and these batteries often cut corners to maximize profits. The protection circuit of the battery itself is prone to problems, resulting in cell expansion. For lithium-ion batteries, when the battery cell expands to a certain extent, it will explode.

2. Poor charger performance: It is most common for chargers to cause battery problems. In many cases, users may not pay much attention to the choice of phone chargers and often pick up a charger to charge. These chargers may be cheap ones sold on the street without a complete protective circuit system, or they may be chargers for household tablet products. Their charging current is likely to be relatively high, and occasional charging problems are not significant. However, if used for a long time, there is a high possibility of battery expansion.

Especially for some users who like to play while charging, leaving their phones in a high temperature environment for a long time. Continuous floating charging at high temperatures can cause side reactions in the electrolyte, which can seriously affect battery life and easily lead to expansion problems.

3. Long term non use of mobile phones: If the phone is not used for a long time, the battery will also experience expansion problems. This is because storing the battery for a long time will drop the voltage to below 2V, and internal chemical reactions will occur, leading to lithium battery bulges. This is also the reason why many friends often find phone battery bulges when dismantling old phones. So if you want to store the battery for a long time, the most reliable way is to regularly charge it to a half charged state.

Regarding the above points, I believe everyone has a general understanding of how to prevent battery expansion. In fact, prevention is not very strict. After all, after using a mobile phone battery for a period of time, it will undergo certain changes compared to when it was first purchased. What we need to do is to ensure its work efficiency and safety as much as possible during the use period. For removable battery phones, it is important to avoid using non original batteries. When choosing a charger, try to avoid non original chargers and avoid playing or overcharging while charging. By achieving the above points, if there are any further issues, it is beyond the user's control.

The reasons for the explosion of mobile phone batteries

How many electronic devices are there in your home or office? Laptops, smartphones, tablets, mobile power supplies, chargers, and more.

Most of the time, electronic devices perform well. However, when they encounter problems, things may become exceptionally bad within a few seconds. The images of Samsung Galaxy Note 7 and electric skateboards exploding and catching fire still occasionally flash in our minds today.

Now let's sort out the reasons for electronic devices such as smartphones and laptops exploding and catching fire, as well as what measures we should take to protect ourselves and your family from them.

The security tests conducted by the author on electronic devices indicate that electronic device users face two biggest threats:

1. Explosive batteries.

2. Contact with high voltage (mainly due to equipment or wire damage, or possibly due to design defects).

Modern rechargeable batteries contain a significant amount of energy in extremely small spaces. Most of the time, the battery will operate normally - releasing energy in a slow and restrained manner. However, if something causes it to discharge quickly, it may cause an explosion and catch fire.

The author has witnessed multiple battery fires, some intentionally tested and some unexpected. I am very clear about how much energy we carry in our pockets or bags.

Defective lithium-ion batteries are very dangerous. It may explode. What I mean by explosion is not the note thrower that startles adults and excites children during party events. A battery explosion will make a loud noise, and the explosive force is enough to shatter the equipment installed on it, creating a rain of glass debris.

However, what you need to worry about is not just the sound of explosions and the accompanying rain of glass debris, as you may also see molten lithium metal ejected and toxic smoke that chokes people.

When you are outdoors in a well ventilated area and away from flammable objects, this intense chemical reaction may not occur. However, it often happens when you least expect it to happen, either when the device is in your pocket or when you are driving on the highway and charging it in the car.

Or when you put it on the bedside table.

Fortunately, explosions and fires do not occur frequently.

The causes of electronic device explosions and fires can be classified into three categories:

1. Production defects: Poor quality batteries (such as Samsung Note7 batteries), component damage caused by assembly line issues, or improper use of components can all lead to equipment explosions and fires.

Interestingly, whenever a device catches fire, the media may blame the production process for any issues. In fact, it may be a problem with the security inspection process. Reputable manufacturers will implement strict safety testing standards.

2. Defective designs and counterfeit products. Some cheap and poorly crafted products may often have problems. Some manufacturers have no idea what they are doing, while others cut corners. Unfortunately, these counterfeit and inferior products often appear in various sales channels, such as eBay and Amazon websites. It may be difficult for ordinary people to judge the quality of a product, as many devices are labeled with fake safety inspection labels.

Many counterfeit and inferior products do not include the safety features provided by well-known manufacturers in their products.

3. The product is damaged during use. It is common for end users to cause products to become unsafe. Throwing devices everywhere, wetting them, charging them with mismatched chargers, and exposing them to sunlight are all bad practices.

High quality products include safety features (including preventing equipment from overheating, overcharging, over discharging, short circuits, and charging with incorrect chargers), which can prevent damaged equipment from becoming unsafe. However, there is no foolproof way to ensure safety.

So, how do you protect yourself and your family from danger?

You cannot purchase expensive testing equipment. In fact, most dangers can be detected without detection equipment. I usually only need to observe with my eyes to identify 90% of unsafe products.

By following the following rules, you can eliminate common hazards of explosions and fires.

1. Purchase branded products from reputable retailers. You may need to spend more money on high-quality chargers or wires, but it's worth it because it involves your and your family's safety. Avoid retailers on eBay and Amazon websites (although it's not right to kill everyone with one blow, it's the only way to ensure safety). If you suspect that you have purchased cheap and low-quality equipment, do not use it again.

If the device is damaged or shows signs of overheating, expansion, or deformation, do not use it. The same goes for chargers and wires. Worn wires are also very dangerous. Most unsafe devices have obvious signs of damage. It is recommended that users inspect the equipment annually and update damaged components in a timely manner.

3. Do not let the device overheat, especially during charging. Do not charge smartphones stored in pockets or sports bags, and do not expose the phone to direct sunlight in the car.

4. Do not ignore devices during charging. Most of us don't pay attention to charging devices, so I suggest you don't place charging devices on flammable objects or near them. A small lithium battery can easily burn down wooden tables or bedroom furniture.

If the device is recalled, follow the manufacturer's recommendations for handling. Don't have a mentality of luck.

If you have any further questions, please consult a professional.

Do not underestimate the speed and degree of danger of ignition in lithium polymer batteries.

If you unfortunately encounter a fire on an electronic device, please follow the following principles to handle it:

1. Do not use water to water the fire! This may make things worse. Only dry powder fire extinguishers or fire blankets can be used.

2. No need to inhale smoke.

3. Don't be a hero. Call the fire department.
