Electrolytic manganese dioxide is a positive electrode material for high performance zn-mn and alkali-mn dry batteries. With the development of the battery industry, especially the demand of environmental protection in recent years, many countries in the world have enacted laws to restrict the production and sales of mercury-containing batteries, and the high-performance alkaline manganese batteries that have entered the market in developed countries have been required to be mercury-free. High performance dry cell requires high degree of electrolytic manganese dioxide, and the anode material used in electrolysis plays an important role. Modern electrolytic manganese dioxide production has adopted titanium anode. This is because titanium has excellent corrosion resistance in many corrosive media, the specific gravity of titanium is small, low temperature toughness is good.
