Electrolytic Manganese Dioxide (EMD)
Product feature :
lower heavy metal PB ,AS ,Cr
lower impurity and lower sulphate
lower chloride
1. Applications of EMD
(1) Primary Battery Industry (Main Market)
- Zinc-manganese dry cells (R-type, LR alkaline batteries)
- Used as the cathode active material for high discharge capacity, good leakage resistance, and stable voltage.
- High-grade EMD is required for alkaline batteries (LR6, LR03).
(2) Lithium Battery & Energy Storage
- Raw material for lithium-manganese oxide cathode materials (LiMn₂O₄)
- Used in some hybrid capacitors and energy storage devices requiring high purity and crystallinity.
(3) Electronic & Industrial Use
- Soft ferrite materials (high-purity grade)
- Catalyst / oxidizing agent in organic synthesis and environmental treatment
- Ceramic colorants and magnetic materials
(4) Metallurgy & Chemical Industry
- Raw material for high-purity manganese metal, manganese salts
- Oxidant in hydrometallurgy processes
2. Main Raw Materials for EMD Production
(1) Manganese Source Raw Materials
- Manganese ore (primary raw material)
- Pyrolusite (MnO₂)
- Psilomelane, rhodochrosite (MnCO₃)
- High‑purity manganese sulfate solution (MnSO₄) – core electrolyte for electrolysis
- Electrolytic manganese metal flakes / manganese powder (for high‑purity routes)
(2) Electrolyte & Additives
- Sulfuric acid (H₂SO₄) – to adjust acidity and dissolve manganese ore
- Ammonium sulfate ((NH₄)₂SO₄) – electrolyte conductivity enhancer
- SeO₂ or selenium compounds – key additive to improve crystal structure and current efficiency
- Other additives: MgSO₄, ZnSO₄, etc., to refine crystal morphology
(3) Water & Energy
- Demineralized / purified water
- Electricity – electrolysis is energy-intensive
(4) Auxiliary Materials
- Anode materials: titanium electrodes (Ti substrate)
- Cathode materials: graphite, lead alloy, or stainless steel
- Filter aids, oxidants (air / oxygen for leaching)
3. Brief Production Principle
- Leach manganese ore with sulfuric acid → prepare manganese sulfate electrolyte
- Purify to remove heavy metals (Fe, Cu, Pb, Ni, Co, etc.)
- Electrolyze in electrolytic cell
- Deposit MnO₂ on anode → harvest, crush, wash, dry → EMD product
4. Key Quality Differences by Grade
- Battery-grade EMD: high purity, low heavy metals, high density, suitable particle size
- Industrial-grade EMD: lower cost, wider impurity tolerance
- High-purity EMD: for lithium batteries and electronics, ultra-low Fe, Cu, Pb, Co
