Abstract

The invention provides a welded steel shell battery cell. The welded steel shell battery cell comprises a cover body assembly, a roll core accommodated in the cover body assembly and a bottom sheet arranged on the cover body assembly, and the cover body assembly comprises an upper cover, a connecting piece fixed on the upper cover and insulating glue clamped between the upper cover and the connecting piece. The upper cover is of a hollow cylindrical structure with an opening in the lower end, the diameter of the bottom piece is larger than that of the upper cover, and the upper surface of the bottom piece is fixed to the lower end of the upper cover in a welded mode so as to block the opening in the lower end of the upper cover. The welded steel shell battery cell provided by the invention is convenient to assemble and relatively high in reliability.

Description

technical field [0001] The invention relates to a welded steel shell electric core. Background technique [0002] Nowadays, the steel shell structure of TWS cells is more complex and complicated than the soft package, so the manufacturing process is also complicated and the efficiency is low. This leads to the fact that although the steel shell cells have many advantages, the complexity and complexity lead to high costs and high assembly costs. Complicated and less reliable. Contents of the invention [0003] Based on this, the present invention provides a welded steel case electric core which is easy to assemble and has high reliability. [0004] A welded steel-case battery cell according to the present invention, the welded steel-case battery cell includes a cover assembly, a winding core accommodated in the cover assembly, and a bottom plate provided on the cover assembly, the cover The assembly includes an upper cover, a connecting piece fixed on the upper cover, and...
