Abstract

PURPOSE:To improve the storability of an alkaline battery and suppress the rise in its internal resistance, by using cross-linked etherealized starch and polyacrylic acid or polyacrylate as a gel-making agent for the cathode depolarizing mix of the battery. CONSTITUTION:3pts.wt. of a mixture of cross-linked etherealized starch and polyacrylic acid or polyacrylate at a weight ratio of 2:1 are mixed with 97pts.wt. of an aqueous solution of 40wt% of KOH to prepare an electrolyte solution in a state of gel. 200pts.wt. of powder of amalgamated zinc are added to the electro- lyte solution and they are mingled and kneaded to prepare a paste-like cathode depolarizing mix to manufacture an alkaline battery of button shape or the like by a conventioal method. Since the cross-linked etherealized starch is used, the velocity of gelling and the stability of the gel are heightened to improve the storability of the battery. Since the polyacrylic acid or polyacrylate is jointly used, the rise in the internal resistance of the battery is suppressed to endhance its performance.
