Wedged step-distributed type porous lithium battery module

Abstract

The invention discloses a wedged step-distributed type porous lithium battery module and relates to the technical field of lithium batteries. The module is characterized by at least comprising a plurality of single batteries and a porous bracket, wherein the outer wall of each single battery is wrapped by an insulating membrane; the outer wall of the insulating membrane is coated by a circle of anadhesive; the adhesive is positioned in the center of the side wall of the single battery; the porous bracket is used for fixing the single batteries; a plurality of circular mounting holes in wedgedstep distribution are formed in the porous bracket; a groove is formed in the circumferential direction in the center of the inner wall of each mounting hole; a fastening screw and a positioning pinare arranged on the side wall of the porous bracket; the single batteries are inserted into the mounting holes; the adhesives are positioned in the positions of the grooves; the single batteries are adhered to the porous bracket through the adhesives. By adopting the technical scheme, the single batteries can be distributed in a limited space as many as possible, the heat density of the module inoperation can be reduced, and the mechanical properties of the module connected with a whole battery group can be improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a wedge-shaped stepped distributed porous lithium battery module. Background technique [0002] For mobile equipment or field operation equipment, power supply in emergency situations is a must. The lithium-ion battery pack can be used repeatedly for a long time as a recyclable backup power supply. At present, outdoor mobile devices have higher and higher requirements for power supplies, and are gradually developing in the direction of high power, high specific energy, light weight, and high reliability. [0003] Lithium battery module is an important part of the lithium battery pack, its space ratio, heat dissipation conduction rate, high specific energy and other indicators play a key role in the performance of the entire battery pack. [0004] There are two main methods for lithium battery modules: the upper and lower mold clamping method, and the bus bar welding a...
