How to prevent lithium battery from bursting?

How to prevent lithium batteries from bursting? All lithium battery bursts are caused by short circuits caused by battery heating. The causes of short circuits include overcharging, overdischarging, direct connection of positive and negative electrodes, and electrolyte leakage. Therefore, when designing lithium batteries, we can start from the following points: 1. Prevent the battery from overcharging exceeding 4.2v; 2. Prohibit the battery to be placed below 2.75v; 3. Install the explosion-proof valve on the metal shell; 4. Prevention Short circuit in the process. Of course, the best way is to design a battery maintenance circuit board. Although this will increase the processing cost of lithium batteries, it is necessary for the safe use of lithium batteries, and all the products of regular lithium battery manufacturers are not immune to this design. Will polymer lithium batteries explode? Polymer lithium batteries are lithium battery products made of flexible packaging and polymer electrolytes. During normal use, they will not burst during storage, unless a strong short-circuit damage is caused by humans. In order to reduce the occurrence of explosion accidents, polymer lithium batteries have been used in more and more occasions. Although lithium batteries are still in the process of replacing other types of batteries, polymer lithium batteries have begun to replace ordinary lithium batteries in certain types of lithium battery types.
