It is not possible to recover a damaged battery yourself.
If the battery is bulging, use your fingers to compress the bulge to a gap, then prick it with a needle, or place it in a low temperature environment to reduce temperature. Remove the lowered battery, then peel off the wrapping paper on the surface of the battery. Then use a needle to pierce a small hole on the surface of the lithium battery. Press with your fingers to expel the gas in the battery and seal the vent holes with tape.
You may have heard of this method. Do not try this method. This is more of a temporary solution than a permanent solution. Even due to pinholes, the battery may be exposed to air and undergo a violent oxidation reaction, leading to adverse consequences.
There are many reasons whymobile phone batteries swell, but in most cases, lithium battery swellings are mainly caused by defects in the design and structure of the battery when it leaves the factory, and the quality is reduced. . There are no protective plates inside the product, positive and negative electrode plates, uneven distribution of alkaline solution (electrolyte), etc.
Many people say that battery swelling is caused by unstable voltage, excessive current, or charging in an environment where the temperature is too high or too low. But this is not the main reason, nor is it a common situation. Low temperature will cause capacity reduction at most. Generally, the storage temperature of electric vehicles is within a reasonable range, and charging is generally limited to a certain voltage. , it is therefore not une common situation.
The most basic reason why cell phone batteries have bulges is that there are obvious quality defects that are causing problems. Once a bulge appears, it is either a short circuit or the internal temperature is too high, potentially causing an explosion. Once the battery explodes, it can swallow up the entire electric vehicle in just ten seconds. the explosion reached up to two hundred degrees. It is very bad.
Can I still use my Huawei mobile phone with a swollen battery?
Lithium battery swelling solution:
1. Do not continue to use the toner cartridge battery. If there is a toner cartridge, please replace it with a new battery in time. . Try not to rely on certain methods taught online to keep your battery going.
2. NOTDon't usually play while you're charging your phone. Stick batteries regularly to avoid dangerous situations.
3. Generally, when charging, pay attention to the choice and size of the charger. The nominal charging voltage of the battery is 3.7 V and the limit voltage is 4.2 V. which exceeds this voltage, thus maintaining a constant current optimally.
Detailed information:
Three possible reasons for battery swelling:
1. Problems with battery manufacturing level, uneven electrode coating and difficult production process;
2. The short circuit reaction will generate a lot of heat, and the soreness will cause resonance, decomposition and gasification, and the battery will swell. ;
3. Additionally, when the battery is used excessively, sinceair is conductive to some extent, swelling will occur. Therefore, if the time is too long, it is equivalent to the first direct contact of the battery and a prolonged short circuit.
What is the reason for the swelling of cell phone batteries?
It can no longer be used. Mobile phone batteries are high-energy lithium batteries. If there are any bulges or swelling, please do not continue to use it to avoid dangerous situations. The lifespan of a cell phone battery is approximately five years. If it is in a humid area, the lifespan of a cell phone battery is approximately five years. four years. When using a cell phone, if it is accidentally soaked in vinegar, the cell phone battery may swell.
At this point you need to replace the cell phone battery. Once the TV batterymobile phone is swollen, the battery may explode when charging or making calls.
Detailed information:
If charging continues, since the negative electrode storage compartment has been filled with lithium atoms, subsequent lithium metal will accumulate on the surface of the negative electrode material, and theseLithium atoms will grow branches from the surface. from the negative electrode towards the lithium ions. These lithium metal crystals will pass through the separator paper and short circuit the positive and negative electrodes.
Sometimes the battery explodes before a short circuit occurs. This is because during the overcharging process, the electrolyte and other materials crack and produce gas, causing the battery shell or pressure valve to swell and rupture, allowing oxygen to enter. enter and accumulate in the battery. The lithium atoms on the surface of the negative electrode react and explode.

What is the reason for cell phone battery swelling
1. Cause analysis
1. Most cell phone batteries usedent of high-energy lithium batteries. Typically, this type of battery swells and swells after use. It is very dangerous to continue to use it when this phenomenon occurs, so once it occurs, the battery must be replaced in time and cannot be used to avoid cell phone explosion.
2. Generally speaking, cell phone batteries will reach the limit of their lifespan after one or two years of use. Cell phone batteries cannot be used for a long time. They can be used up to three times.After one or two years, various problems will occur with the battery of mobile phones. The main reasons for these problems are battery quality issues and excessive usage.
3. Lithium battery is a metal battery If this battery is exposed to air for a long time, it willwill expand and explode easily. Lithium batteries are also metal objects that can be charged and discharged, so they will react chemically with oxygen. It is relatively less durable.
2. How to deal with it
When your cell phone battery swells, you should not continue to use it and you should clean it in time. But cleaning it on time does not mean that you can just throw it in the trash or throw it into flammable and explosive materials. Once the cell phone battery swells, it means it will explode at any time. You should also be careful when handling lithium batteries because if you are not careful you can harm others and yourself. To deal with swollen cell phone batteries, you can choose a box or bag, wrap the battery and throw it into a trash can thatputs recycling of metal objects. Don't just throw them in the trash at home. Rechargeable batteries will produce certain toxic substances when exposed to water, which will affect your health.
Fever prevention and solutions:
1. Prevention methods:
Cell phone At. normal room temperature, it is normal that the heat does not exceed 60°C and will not damage the battery.
b. Do not use a high current charger for too long. Charging for too long will damage the battery and generate heat.
c. It is better to use original or reputable chargers.
d. If you are not in a hurry to use it, it is recommended to use a pedestal charger (slow charging method) to avoid heating the battery. It is best to use the original charger of the mobile. phone.
e. If youFeel the phone is a little warm when you listen to music or charge the battery, you can use *#0228# to check its temperature. If it exceeds 60℃, return to sleep mode immediately. or use another battery. If you charge, stop immediately.
The difference between the two types of batteries
The difference between the two types of batteries, the positive and negative electrode materials used in lithium -polymer ion batteries and liquid lithium The ions are all the same, the positive electrode material is divided into lithium cobalt oxide, lithium manganate, ternary material and lithium iron phosphate material, the negative electrode is graphite and the principle of operation of the battery is basically the same. . The main difference between them is the electrolyte. Liquid lithium-ion batteries use liquid electrolytes, while lithium-ion batteriesLithium-ion polymers use solid polymer electrolytes instead. The chemical properties of lithium are very active and easy to burn. As the battery is charged and discharged, the interior of the battery continues to heat. The gas generated during the activation process expands and the internal pressure of the battery increases. When the pressure reaches a certain level, if the outer shell is damaged, it will rupture, causing expansion, leakage, fire or even explosion. Since lithium-ion polymer batteries use solid electrolytes, they will not leak or explode, but only expand, making them safer.
Comparing the two types of batteries, lithium polymer batteries are safer than lithium ion batteries and more expensive in terms of cost. However, the problem of swelling and bulging will still occur. to do with usage habitsof the user.
Different types of batteries have different reasons for swelling. In the era of smartphones, whether it is an all-in-one machine or not, the batteries used in mobile phones on the market are mainly lithium-ion. batteries and lithium-ion polymer batteries. Other batteries have either been eliminated because they were too backward, or they are in the conceptual stage and have not been used on a large scale.
