ABSTRACT:
An anode can capable of preventing leakage of liquid, method of fabricating the same, and battery using the anode can and method of fabricating the same is provided. An anode can is formed of a material formed of a stack of layers including an aluminum alloy and stainless steel layers formed on the aluminum alloy layer and it includes a flat, center portion and a peripheral side wall contiguous to and surrounding the flat center portion. The aluminum alloy layer located at the peripheral side wall is thinner than the aluminum alloy layer located at the flat center portion. At an edge of the peripheral side wall, the aluminum alloy and stainless steel layers have their respective end surfaces aligned substantially in a single straight line in a plane substantially perpendicular to an outer peripheral surface of the peripheral side wall.
