Method for manufacturing an aluminum case of a battery

A method for manufacturing an aluminum case of a battery, wherein the battery comprises a cover plate, the cover plate is closed at an opening of the aluminum case to form an outer case of the battery, the aluminum case comprises a plate body, and the method comprises:

• attaching an insulating layer to at least one surface of the plate body with an adhesive layer, wherein the plate body has an inner surface and an outer surface, and wherein the insulating layer covers at least one of the inner surface and the outer surface, and wherein the adhesive layer is located between the insulating layer and the plate body,
• stamping, before the adhesive layer is cured, the plate body attached with the insulating layer to form the aluminum case in a predetermined shape, wherein during the stamping of the plate body, the insulating layer is movable relative to the plate body since the adhesive layer is not cured;
• curing the adhesive layer after the stamping of the plate body is completed so that the insulating layer is fixed to the plate body, thereby avoiding detachment of the insulating layer and the plate body on the aluminum case.
