BUTTON-TYPE ALKALINE BATTERY

摘要

PURPOSE:To produce a battery with high capacity and high reliability by using a positive case formed by a material prepared by plating a stainless steel plate with nickel. CONSTITUTION:A positive case 9 is formed by a material prepared by performing nickel plating on the surfaces of a stainless steel plate containing 15-17wt% o chronium and 13-15wt% of nickel. The thickness of the plate can be reduced without decreasing the structural strength of the positive case 9. Accordingly, it is possible to reliably increase the capacity of the battery by increasing the internal volume of the positive case 9.
