PURPOSE:To make an electrolytic solution to be securely supported and thereby to enhance the discharge characteristics of a battery, by loosely fitting to a core type body plural kinds of preliminarily molded positive electrode bodies with different internal and external diameters, in order to form a unit and by disposing the unit in a positive electrode can, and by pressing the unit onto the internal surface of the can by a sleeve like punch. CONSTITUTION:Plural kinds of 2a-2d or the like of preliminarily molded positive electrode body having a short pipe shape with different internal and external diameters are loosely fitted to a rod-like core-type body A and then disposed in the positive can 1; then by pressing a sleeve-like punch B, a positive electrode body is pressed to touch the internal surface of the positive electrode can to reform the positive electrode body. In the case of pressure-remolding by a sleeve like punch B, a load is applied separately, and thereby, the positive electrode body with ununiform distribution of surface density provided with a large portion easily absorbing the electrolytic solution, can be obtained. This method can be applied to manganese dioxide-zinc battery, or the other battery system. |
