AI Technical Summary

Technical Problem

When the casing thickness is too thin, the assembly between the casing and the cover plate assembly becomes more difficult, affecting the connection strength, sealing performance, and battery appearance.

Method used

A thickened portion and a support portion are connected near the opening end of the housing. The thickened portion is stacked with the main body, and the support portion extends radially to limit the cover plate assembly, forming a reliable connection.

Benefits of technology

It improves the sealing and safety of the battery cells, reduces assembly difficulty and cost, and mitigates the impact of heat and foreign objects on the storage space.

Abstract

The application provides an electric core and a battery. The electric core comprises a shell, a cylindrical main body part, and a containing space formed by the main body part; at least one end of the main body part in the axial direction is configured as an open end; a thickening part and a supporting part are connected to the inner side of the main body part close to the containing space; the thickening part is arranged in a stack mode close to the open end of the main body part; and the supporting part extends towards the containing space in the radial direction of the main body part; a cover plate assembly is connected to the open end; the cover plate assembly comprises a cover plate body connected to the side of the thickening part away from the main body part and abutting against the surface of the supporting part close to the open end. The electric core provided by the application can ensure reliable connection between the cover plate body and the thickening part by connecting the thickening part arranged in a stack mode to the main body part at the position close to the open end of the main body part, so as to increase the total thickness of the shell at the position.
