Abstract

The invention relates to a cylinder type secondary battery composite structure. The invention discloses a power lithium ion battery composite structure, comprising cylinder type battery combination, wherein the top of the cylinder type battery combination has an anode injection moulding plate, an anode current collector and anode fireproofing and shockproof fixation material, the bottom of the cylinder type battery combination has a cathode injection moulding plate, a cathode current collector, and cathode fireproofing and shockproof fixation material, round holes for placing batteries are fixed on the anode and cathode injection moulding plates, wherein the anode current collector is connected with an anode post of the cylinder type battery combination, the anode fireproofing and shockproof fixation material is placed between the cylinder type battery combination and the anode, the cathode current collector is connected with the cathode post of the cylinder type battery combination, the cathode fireproofing and shockproof fixation material is placed between the cylinder type battery combination and the cathode current collector, and the anode and cathode injection moulding plates are connected by assembling bolt. The composite structure of the invention is firm, has good resistance to shock, enhances anode and cathode leadout current-carrying capacity, more safe, and more convenient to maintenance.

Description

technical field [0001] The invention relates to a cylindrical secondary battery assembly structure. In particular, it relates to a combined structure of a power lithium-ion battery. Background technique [0002] The existing traditional cylindrical secondary battery combination structure is: the original cylindrical batteries are arranged side by side, and the single cells are bonded together with hot melt adhesive between the batteries, so that the During the charging and discharging process, the hot melt adhesive will melt after the battery heats up, causing the single battery to loosen. possible. Damaged batteries must be replaced after the positive and negative poles of each battery are damaged during the repair process, and the battery is difficult to disassemble. Disassembly and assembly of the battery will also cause battery damage and be scrapped. Contents of the invention [0003] The purpose of the present invention is to provide a power lithium ion battery co...
