Lithium battery advantage

25.9V Li ion battery

Lithium-ion batteries are currently divided into three main categories, namely square, cylindrical, and soft pack; the square and cylindrical shells are mainly made of aluminum alloy, stainless steel and other hard shells, while the shell of the soft pack is made of aluminum plastic film. Compared with square and cylindrical housings, what are the main advantages of soft pack lithium batteries?

Good safety performance

 The electrolyte of the soft-pack battery has less leakage, and the
