Preparation of CMD for Alkaline Zinc-Mangenese Battery
Abstract:
The chemical manganese dioxide(CMD) for alkaline zinc manganese battery was prepared through direct oxidation or V-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.
