▎ 摘　　要

NOVELTY - The chip is prepared by, between lamination process and coating process, placing 0.3-0.5 mm graphene sheet, and placing two graphene sheets on laminated battery core bottom layer and top layer. The two graphene sheets are tightly fixed by high temperature adhesive tape so that the laminated electric core hardness is enhanced, which is convenient for the electric core to be fed into aluminum square tube. The graphene sheet has the function of absorbing electrolyte and has quick radiating function, ensuring the service life of the finished electric core and effective control of heat management. USE - Lath battery chip. ADVANTAGE - The graphene sheet has the function of absorbing electrolyte and has quick radiating function, ensuring the service life of the finished electric core and effective control of heat management. The electric core internal temperature is improved to obtain the controllable range, the electric core is stacked into battery pack and then heat management is effectively controlled. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of lath battery chip.
