Electrolytic manganese dioxide is a cathode material for the manufacture of high-performance zinc-manganese and alkali-manganese dry batteries. With the development of the battery industry, especially the demand for environmental protection in recent years, many countries in the world have legislated to restrict the production and sales of mercury-containing batteries, and high-performance alkali-manganese batteries in developed countries have been required to be mercury-free. High-performance dry batteries have high requirements for electrolytic manganese dioxide, and the anode material used in electrolysis plays a crucial role. Modern electrolytic manganese dioxide production has used titanium anodes. This is because titanium has excellent corrosion resistance in many corrosive media. Titanium has a small specific gravity and good low temperature toughness.
