Abstract

PURPOSE:To increase discharge performance at a low temperature by using the mixture of cross linking sodium polyacrylate and non-cross-linking sodium polyacrylate as a gelling agent of an electrolyte. CONSTITUTION:The mixture of cross linking sodium polyacrylate and non- cross-linking sodium polyacrylare is used as a gelling agent and added to an alkaline electrolyte and mixed to prepare a gel-like electrolyte. Amalgamated zinc powder is mixed with the gel-like electrolyte to prepare a paste-like anode 2. As the cross linking sodium polyacrylate mentioned above, for example, sodium salt of multibranching polyacrylic acid obtained by adding the molecular chain of other polyacrylic acid to the side chain of straight chain polyacrylic acid, or sodium salt of polyacrylic acid copolymer obtained from acrylic acid and polyfunctional group monomer such as methylene bisacrylamide, divinylbenzene is used. As the non-corss-linking sodium acrylate, usual sodium polyacrylate is used.
