Precautions for the use of lithium-ion polymer batteries
1. Pay attention to the short circuit
Polymer lithium-ion batteries are prone to short circuits during charging. Including: internal short circuit, external short circuit, etc. Although most lithium-ion batteries now have short-circuit protection circuits and explosion-proof wires, in many cases, this protection circuit may not work in various situations, and the explosion-proof wires can only play a limited role. .
Polymer lithium-ion batteries, if the charging time is too long, the possibility of swelling will increase. The chemical properties of lithium are very active, and it is easy to burn. When the battery is charged and discharged, the temperature inside the battery continues to rise, the gas generated during the activation process expands, and the internal pressure of the battery increases. When the pressure reaches a certain level, if the shell is scratched, it will burst , causing leakage, fire, or even explosion. And a polymer lithium-ion battery just swells.
