Electrolytic manganese dioxide is a positive electrode material for manufacturing high performance zinc-manganese and alkaline-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 the high performance alkaline manganese batteries for market access in developed countries have required no mercurization. High performance dry batteries have high requirements for electrolyzing manganese dioxide, and the anode materials used for electrolysis play a crucial role.
