EMD Usage & Applications
Used as main raw material in the battery industry:
  • Electrolytic manganese dioxide is an excellent depolarizing agent for batteries, offering large discharge capacity, strong activity, small volume, and long service life.
  • It is a critical component of the battery cathode mix in today's alkaline & lithium-ion batteries.
Other field applications:
  • Oxidizing agent in fine chemical production processes.
  • Decolorizing agent in the glass industry.
  • Raw material for Fe Mn alloy in the steel-making industry.
  • Used in fireworks, water purification, medicine, fertilizers, and fabric printing and dyeing.
