1. Analysis of causes
1. Most cell phone batteries use high-energy lithium batteries. Typically, this type of battery swells and swells after prolonged 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 their lifespan limit after one or two years of use. Cell phone batteries cannot be used for a long time. They can be used for up to three years. After one or two years, various problems will arise with the cell phone battery. The main reasons for these problems are battery quality issues and excessive usage.
3. The lithium battery ist a metal battery if this type of battery is exposed to air for a long time, it will 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 mobile phone battery swells, you should not continue to use it and 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 ora bag, wrap the battery and throw it in a trash can that allows metal objects to be recycled. 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.
Detailed information:
1. When the mobile phone is at normal room temperature, it is normal that it will not generate more than 60℃ heat and will not damage the battery. .
2. Do not use a high current charger for too long. Charging for too long will damage the battery and generate heat.
3. It is better to use original or reputable chargers.
4. If you are not in a hurry to use it, it is recommended to use a stand charger (char methodslow) to prevent the battery from heating up. It is best to use the original charger. of the cell phone.
5. If you feel that 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 standby immediately or. use another battery. If you charge, stop immediately.
First of all, it must be a lithium-ion battery
Then the plate inside is the anode of the LiCoO2 oxide and lithium carbon compound form the cathode on the copper plate, filled with glue in the middle Lithium organic solvent
So when you accidentally short circuit, over discharge, the solvent in the discharge process and the two polar plates act on them to discharge, and a strong chemical reaction occurs, hydrogen will be produced.
And in the case of temperaturehigh and sparking, once hydrogen when ignited, it will cause combustion, but generally it will not explode but only burn. Because the battery is currently manufactured in accordance with international safety standards, the battery cannot explode under any circumstances and can only burn. The principle is to use a special fuse, punch a hole and ignite the released hydrogen, so a small amount of hydrogen will only burn and burn the battery body, but will not cause any damage. explosion due to large quantity. of hydrogen accumulating and burning instantly
So combustion is a normal phenomenon, when disassembling the battery later, be careful not to damage its internal plates, otherwise these things will happen in case of short circuit, and it will also happen in case of overcharging and overdischarging
