Abstract

The utility model relates to a lead-lithium mixed lithium battery structure which comprises a shell, a main battery pack, an auxiliary battery pack and a blocking part are arranged in the shell, and the blocking part is arranged between the main battery pack and the auxiliary battery pack to block heat transfer. The insulation film and the heat insulation film are sequentially connected to the two sides of the blocking piece from inside to outside. The insulating film is made of a polyethylene material, and the heat insulation film is made of a polypropylene material. According to the utility model, the blocking part is arranged between the main battery pack and the auxiliary battery pack and is used for blocking heat transfer between the main battery pack and the auxiliary battery pack, so that the main battery pack and the auxiliary battery pack do not interfere with each other and are controlled by the overall temperature of the battery.
