PURPOSE:To maintain performance and reduce cost when a negative electrode terminal plate housing a negative electrode whose principal component is hardened zinc by cladding the battery inner surface side of a stainless steel matrix with copper and nickel-plating the outer surface side. CONSTITUTION:A negative electrode terminal plate 9 housing a negative electrode 8 in which granulated hardened zinc is diffused in a gel form by means of alkaline electrolytic solution and a gelatinizing agent is formed by cladding the battery inner surface side of a stainless steel matrix 5 with copper 6 by using the hot rolled method, etc. and nickel-plating 7 the outer surface side by using the electroplating method, etc. Then, a button type alkaline battery is formed by combining positive electrode black mix 2 housed in a positive electrode can 1 that is nickel-plated on stainless steel, separator 3, gasket 4, etc. As a result, the incovenience resulting from pinholes can be eliminated like copper plating and the cost of an alkaline battery can be reduced by using the battery inner surface side only as the cladding section. |
