Abstract: Disclosed are a battery housing and a battery. The battery housing includes a bottom shell and a cover. The cover includes an outer contact layer, an insulating layer, and an inner contact layer. The electrode contact portion of the outer contact layer passes through the insulating layer and the inner contact layer to be electrically connected to one pole of a battery cell. The other electrode of the battery cell can be electrically conducted with the bottom shell. The inner contact layer and the bottom shell are configured to be welded for packaging the battery cell. Since the inner contact layer and the outer contact layer of the cover are pre-insulated, the inner contact layer and the bottom shell need to be welded, and the insulating film is not needed, thereby simplifying the packaging process of the battery and improving the packaging efficiency.

The cover includes an outer contact layer, an insulating layer, and an inner contact layer. The electrode connecting portion of the inner contact layer is electrically connected to one pole of the battery cell. The other pole of the battery cell is electrically connected to the bottom shell. Since the inner contact layer and the outer contact layer are insulated through the insulating layer, the bottom shell is also insulated from the inner contact layer, thereby preventing the two electrodes of the battery cell from being mutually connected and short-circuited. Since the inner contact layer and the outer contact layer of the cover are pre-insulated, the insulating film is not needed, thereby simplifying the packaging process of the battery and improving the packaging efficiency.
