Problems solved by technology

[0003] In the composition of the existing square lithium-ion power battery, the top cover is an accessory composed of multiple parts. At present, in the design of the existing square lithium-ion power battery, insulating plastic is generally designed under the top cover. The function is to insulate the top and design buckles and brackets for assembly, but the design of this structure increases the volume occupation of the internal height space of the shell, and also increases the weight of the top cover assembly, which further affects the overall energy of the battery. density

Abstract

The invention provides a battery cover plate assembly and an assembling method and a manufacturing method thereof, and a battery core. The battery cover plate assembly comprises a cover plate, an insulating film and a supporting sheet, wherein a plurality of buckle male heads are arranged on the cover plate, the insulating film is provided with a through hole for the buckle male heads to pass through, the supporting sheet is provided with a buckle female head matched with the buckle male head, and the insulating film is assembled between the cover plate and the supporting sheet. By optimizingthe structure of the plastic at a lower part of the cover plate, the internal space of a top cover can be optimized to a great extent, so the upper space of the battery can be saved, the weight of thecover plate assembly is reduced, and the energy density of a lithium ion power battery is improved.

Description

technical field [0001] The present application relates to the field of lithium-ion battery equipment, in particular to a battery cover assembly, an assembly method and a manufacturing method thereof, and a battery cell including the battery cover assembly. Background technique [0002] In recent years, with the rapid development of lithium-ion power battery technology, the penetration rate of new energy vehicles is also increasing. As the most important component of new energy vehicles - batteries, their energy density directly affects the performance of vehicles such as mileage. How to improve the energy density in the design process of power batteries is the requirement of the market and the development direction of the industry. [0003] In the composition of the existing square lithium-ion power battery, the top cover is an accessory composed of multiple parts. At present, in the design of the existing square lithium-ion power battery, insulating plastic is generally des...
