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 platesare 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 combined structure. Specifically, it relates to a power lithium ion battery combined structure. Background technique [0002] The existing traditional cylindrical secondary battery assembly structure is: the original cylindrical battery is arranged side by side, and the single cell and the single cell are bonded together with hot melt glue between the battery and the battery. During the charging and discharging process, the battery heats up and causes the hot melt glue to melt, causing the single battery and the single battery to loosen, and the battery pack vibrates during use, causing the positive and negative poles to lead out the tabs and wear the insulating layer, causing the battery to explode or battery efficiency Possible. Damaged batteries must be replaced after the positive and negative poles of each battery are damaged during the repair process, and the batteries are difficult to disassem...
