Electrolytic Manganese Dioxide Production

MnSO4 + 2H2O → MnO2 + H2SO4 + H2

अवलोकन

Electrolytic manganese dioxide (EMD) is produced by electrolyzing manganese sulfate solution in sulfuric acid at 90–98°C. MnO₂ deposits on the titanium anode as a dense, high-purity gamma-phase material with superior electrochemical activity compared to natural or chemical MnO₂. EMD is essential for high-performance alkaline and lithium batteries.
