Abstract

A cover assembly and a battery are disclosed. The cover assembly is configured to cover a housing provided with an accommodating cavity in the battery and includes a top cover and an anode piece. The top cover is configured to be connected to the housing and cover the accommodating cavity, the top cover has a top surface away from the accommodating cavity, and the top surface is recessed towards the accommodating cavity to form a counterbore. The anode piece is disposed on the top cover, the counterbore is configured to accommodate the anode piece, the anode piece has an upper surface away from the accommodating cavity, and the upper surface is coplanar with the top surface; or the upper surface is closer to the accommodating cavity with respect to the top surface.

Abstract

The present application relates to a covering assembly, a method for machining a covering assembly, and a battery. The covering assembly is applicable to a battery which has a case provided with an accommodating cavity, and comprises a top cover, an insulating sheet and a positive electrode plate. The top cover is used to cover the accommodating cavity, and comprises a first connecting layer having a molecular structure different from that of other portions. The positive electrode plate comprises a second connecting layer having a molecular structure different from that of other portions. The insulating sheet is stacked between the first connecting layer and the second connecting layer, and is connected to the first connecting layer and the second connecting layer in a hot-melt manner.
