<P>PROBLEM TO BE SOLVED: To provide an alkaline battery capable of keeping an excellent heavy load discharge characteristic even after high-temperature storage. <P>SOLUTION: This alkaline battery is provided with: a metallic positive electrode case with a nickel-cobalt alloy layer formed on its inside surface; a positive electrode mix stored in the positive electrode case and contacting the nickel-cobalt alloy layer; and a zinc negative electrode disposed by facing the positive electrode mix through a separator; and the positive electrode mix contains at least nickel oxyhydroxide as an active material. Oxidation by the nickel oxyhydroxide of the positive electrode case can surely be prevented by the nickel-cobalt alloy layer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
