What is the reason for lithium battery swelling.

What is the reason for lithium battery swelling.

1.The difficulty in the manufacturing level of lithium batteries is the uneven electrode coating and uneven production process;

2. The short reflection of a short circuit fault converts a large amount of heat, causing the electrolyte solution to dissolve and vaporize, resulting in lithium ions;

3. If the battery pack is not used for a long time and the battery is over discharged, it will also produce bulging phenomenon;

4. Poor quality of lithium battery chargers. The charging head is made of fake or defective electronic devices, with high heat and inaccurate main parameters, making it impossible to control the battery charging limiter;

5. The charging time of the battery is too long. After overcharging, if too much battery is charged, it will cause a large amount of steam to wash the electrodes, causing the lithium battery in the active material to fall off, reducing the number of battery cycles, accelerating the water shortage rate of the charging battery, endangering the dissolution of the lithium battery, causing the battery temperature to rise, and making it fully charged into a drum shape;
