Problems solved by technology

[0005] First, the side of the existing module is fixed with structural glue, which will cause uneven glue application;
[0006] Second, glue application will pollute other areas of the module;
[0007] Third, glue application needs to wait for the glue to dry out, reducing the production efficiency of the production line;
[0008] Fourth, it is difficult to insert the cell stack into the shell after the glue is applied, and glue overflow will occur at the same time

Abstract

The invention discloses a battery module and an assembling method thereof. The battery module comprises a battery cell assembly and a shell assembly, wherein the battery cell assembly comprises a plurality of battery cell units which are arranged side by side, the battery cell assembly is arranged in the shell assembly, the battery cell assembly is bonded with the shell assembly through a double-faced adhesive tape layer of an adhesive tape, the adhesive tape comprises an isolation layer and a double-faced adhesive tape layer, and the double-faced adhesive tape layer is bonded on one surface of the isolation layer. The battery cell assembly and the shell assembly of the battery module are bonded through the double-faced adhesive tape layer, the adhesive layer is uniform, other areas of themodule cannot be polluted in the assembling process, the battery module can be used immediately after being pasted, and adhesive overflowing is avoided.

Description

Technical field [0001] The invention relates to the field of soft pack batteries, in particular to a battery module and an assembly method thereof. Background technique [0002] Soft-packed lithium-ion batteries are popular because of their high energy density, good safety, and lightness. They have been widely used in 3C digital electronics, pure electric vehicles and hybrid electric vehicles. [0003] At present, the battery cell stack (also called the battery cell assembly) in the soft package module generally has a certain interference fit with the side plate in the width direction. This interference fit (compressed foam, the pressure is between 20Kpa and 40Kpa). Between) to improve the cycle life of the battery. At the same time, in order to improve the impact resistance of the module, the cell stack and the module are pasted together by structural glue, and the adhesive surfaces of the two are the bottom and side of the cell respectively. [0004] This method has the following...
