Abstract

PURPOSE:To prevent any increase of the internal pressure of an alkaline manganese battery which is due to misuse or gas generation during the last stage of the discharge, by adding a given amount of cadmium oxide to gamma-manganese dioxide in preparing a positive mixture. CONSTITUTION:A positive mixture 1 consisting of a mixture of gamma-MnO2 powder with graphite powder, together with a positive ring 3, is compressed and molded within a positive case 2. The former positive mixture 1 is added with CdO, in order to make H2 gas generated by misuse or the like disappear; the ratio of CdO to the gamma-MnO2 powder should by 1-10wt%.
