Abstract

The invention discloses a lithium ion battery composite pole cover plate and assembling equipment thereof. The lithium ion battery composite pole cover plate comprises a lower insulation pad, the upper end of the lower insulation pad is fixedly connected with a top cover plate, a mounting groove is formed in the middle of the top cover plate, an anti-explosion valve is mounted in the mounting groove, and an anti-explosion valve patch is arranged at an inlet of the mounting groove; a positive pole is mounted at one end of the top cover plate, a negative pole is mounted at the other end of the top cover plate, and the upper ends of the positive pole and the negative pole are connected with the top cover plate through pole plastic; according to the composite pole cover plate disclosed by the invention, the space of the cover plate is greatly utilized, so that the internal space of a battery cell is increased, and the external height of the battery cell is reduced; defects of the copper-aluminum composite material are avoided, and safety risks of liquid leakage and short circuit of the battery cell cannot be caused even if the copper-aluminum composite material fails.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a lithium ion battery composite pole cover plate and assembly equipment thereof. Background technique [0002] Lithium-ion batteries have the advantages of light weight, high voltage, long charge and discharge life, low self-discharge rate, wide operating temperature range, etc., and have been widely used in digital cameras, mobile phones, power tools and other fields. With the development and maturity of electric vehicle technology, lithium-ion battery technology for automobiles has become the core technology of electric vehicles, and has become the main direction of most new energy vehicle companies. [0003] The installation structure of the pole on the cover plate of the aluminum shell of the existing lithium-ion battery is complicated, and the sealing performance is not good. The failure of the copper-aluminum composite material will lead to the safety risks of...
