What is the important reason why the battery swells and bursts

1. Poor battery maintenance circuit or no maintenance circuit: This situation often occurs in mobile phones with removable batteries. Many users like to buy relatively cheap non-original batteries, and these batteries usually cut corners in order to maximize profits. The battery's own maintenance circuit simply presents a problem, and the battery cell swells. Regarding lithium batteries, the cell swells to a certain extent and explodes. 2. Charger function is not good: The battery problem caused by the charger should be the most widespread. In many cases, users may not mind the choice of mobile phone charger, and often take a charger at hand for charging. These chargers may be cheap chargers sold on the street without a complete maintenance circuit system, or they may be chargers for household tablet products. The charging current is likely to be relatively large, and occasionally the charging problem is not big, but if it takes a long time Application, it is very likely that the battery will swell. Especially some users like to play while charging, leaving the mobile phone in a high temperature environment for a long time. Continued floating charging at high temperature will cause the electrolyte to have side effects. Doing so for a long time will seriously affect the battery life and swell. The problem is presented very simply. 3. If the mobile phone is not used for a long time: If the mobile phone is not used for a long time, the battery will also show a problem of swelling. This is because the battery will be stored for a long time, the voltage will drop below 2V, and internal chemical reactions will occur, causing the lithium battery to swell , This is the reason why many friends will find the cell phone battery bulge when disassembling the old cell phone. So if you want to store the battery for a long time, the most reliable way is to charge it to a half-charged state on time.
