How to protect the circuit of lithium battery
Lithium battery manufacturers will take you to understand that due to the high energy density of lithium ion batteries, it is difficult to ensure the safety of the battery. Lithium battery manufacturers have found that in an overcharged state, the energy will be excessive when the battery temperature rises, so the electrolyte decomposes to produce gas, which may cause spontaneous combustion or rupture due to the increase in internal pressure; on the contrary, in the over-discharged state, the electrolyte will decompose due to decomposition. This leads to deterioration of battery characteristics and durability, thereby reducing the number of rechargeable times.
