Preparation of CMD for Alkaline Zinc-Mangenese Battery

Department of Chemistry, Fujian Nomal University, Fuzhou 350007

Received Date: 3 August 1997
Revised Date: 10 November 1997

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.
