Abstract

The invention provides a nested steel shell battery cell. The nested steel shell battery cell comprises a lower cover, a roll core accommodated in the lower cover and a cover body assembly arranged on the lower cover, 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, and the upper cover and the lower cover are both of hollow cylindrical structures. The outer diameter of the upper cover is smaller than the inner diameter of the lower cover, the outer surface of the upper cover abuts against the inner surface of the lower cover, and the upper cover is fixed to the lower cover in a welded mode. The nested steel shell battery cell provided by the invention is relatively good in sealing performance and convenient to assemble, and the manufacturing efficiency of the steel shell battery cell is improved, so that the cost is reduced.

Description

technical field [0001] The invention relates to a nested 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 high cost of the steel shell cells although they have many advantages. Contents of the invention [0003] Based on this, the present invention provides a nested steel shell cell with good sealing performance, easy assembly and high manufacturing efficiency. [0004] A nested steel case electric core of the present invention comprises a lower cover, a winding core accommodated in the lower cover, and a cover assembly provided on the lower cover, the cover assembly includes an upper cover, a fixed The connector on the upper cover and the insulating glue sandwiched between the upper cover and the connector, the upper cover and the lower cover are both hollow cylindrica...
