What are the reasons for the bulging of polymer lithium battery packs

1. The problem of the manufacturing level of lithium battery packs, the electrode coating is uneven, and the processing technology is relatively rough; 2. The violent reaction of the short circuit generates a large amount of heat, which in turn causes the electrolyte to analyze and vaporize, and the lithium battery bulges; 3. In addition If the polymer lithium battery pack is not used for a long time, the bulging phenomenon will occur, because the air is conductive to a certain extent. Therefore, if the battery is left for too long, it is equivalent to direct contact between the positive and negative electrodes of the battery and a chronic short-circuit occurs. 4. Reasons for the poor quality of lithium battery chargers. The charger uses inferior materials, refurbished or inferior components, heat generation, and inaccurate parameter drift, which makes the charging voltage limit out of control, causing the internal gas compression of the lithium battery to deform the battery shell, causing the battery shell to deform and burst or even explode. 5. The charging time is too long. If over-charging will cause a large amount of gas to wash the plates, cause the active material inside the lithium battery pack to fall off, shorten the battery life, accelerate the battery loss rate, affect the analysis of the electrolyte, increase the battery temperature, and make it full!
