Abstract

Abstract: The chemical manganese dioxide(CMD) for alkaline zinc manganese battery was prepared through direct oxidation or γ-MnO² by chlorine gas in sulfuric acid medium at 85～90 ℃ with addition of MgO as pH regulator, followed by protonation with KMnO⁴ solution. The CMD obtained was an n-type semiconductor and showed an improved electrochemical property. The sample battery LR03 showed a good discharge behavior.

Key words: chemical manganese dioxide, preparation, alkaline zinc-manganese battery
