【摘要】 以直接氧化法生成的初级二氧化锰经饱和水蒸汽处理后，进行重质化处理，制成碱性锌锰电池用化学二氧化锰，所研制样品表现出ｎ－型半导体特征，从Ｘ射线衍射、热重分析的测试，发现成品的理化性能和结合水含量有较大的改进，电化学活性也有较大提高，所制成ＬＲ０３实体电池电性能优良．更多还原

【Abstract】 The chemical manganese dioxide(CMD) for alkaline zinc manganese battery was prepared through direct oxidation or γ MnO 2 by chlorine gas in sulfuric acid medium at 85-90 ℃ with addition of MgO as pH regulator, followed by protonation with KMnO 4 solution. The CMD obtained was an n type semiconductor and showed an improved electrochemical property. The sample battery LR03 showed a good discharge behavior.更多还原
