Problems solved by technology

[0003] However, because the outer packaging of the flexible lithium-ion battery cell is a layer of aluminum-plastic film, the entire cell is soft, the compactness of the battery is reduced, the cell packaging film is easily punctured, and the safety performance is reduced.
In addition, after the batteries are grouped, due to the large amount of parallel series, during the high-current charging and discharging process, due to the heating of the battery core, the heat accumulation of the battery pack, the internal temperature of the battery rises, or the internal temperature of the battery is not balanced, resulting in battery consistency. Reduced, the battery core will swell, affecting the consistency and balance of each battery after the battery is grouped, and reducing the cycle life of the battery

Abstract

The invention relates to a battery module, comprising multiple battery monomers and multiple heat conducting partition plates. The heat conducting partition plates and the battery monomers are mutually superposed in arrangement, the heat conducting partition plates are provided with a partition plate main body and multiple side plates connected with the partition plate main body, the partition plate main body and the multiple side plates form a containing space of the battery monomers together, and the edges of the side plates, which are far away from the partition plate main body, are bent and stretched to form heat dissipation fins.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to battery modules. Background technique [0002] Lithium-ion batteries, because they can be charged and discharged repeatedly, have a long service life, relatively small volume and mass, and relatively good safety, specific capacity, self-discharge rate, performance and price, have become the main products for making high-power power supplies. [0003] However, because the outer packaging of the flexible lithium-ion battery cell is a layer of aluminum-plastic film, the entire cell is soft, the compactness of the battery is reduced, the cell packaging film is easily punctured, and the safety performance is reduced. In addition, after the batteries are grouped, due to the large amount of parallel series, during the high-current charging and discharging process, due to the heating of the battery core, the heat accumulation of the battery pack, the internal temperature of the battery...
