Applications
- Glass industry and enamel ceramics (as colorant, decolorizer, iron remover).
- Catalyst and oxidizer in synthetic industries.
- Depolarizer for dry batteries.
- Manufacturing of metallic manganese, special alloys, manganese cast iron, gas masks, and electronic materials (e.g., ferrites).
- Catalyst in chemical experiments.
Electrolytic Manganese Dioxide (EMD) is an excellent depolarizer for batteries. Compared to dry batteries produced using natural manganese dioxide, EMD offers advantages such as higher discharge capacity, stronger activity, compact size, and longer lifespan, making it a crucial raw material in the battery industry.
Physical State & Applications
In addition to being a primary material for batteries, EMD is widely used in other fields, including:
- Fine chemical production as an oxidizing agent.
- Raw material for manganese-zinc ferrite soft magnetic materials.
Due to its strong catalytic, oxidation/reduction, ion exchange, and adsorption capabilities, EMD—after processing and shaping—serves as a high-performance water purification filter medium. Compared to conventional filter materials like activated carbon and zeolite, EMD exhibits superior decolorization and metal removal efficiency.
Why Choose Our MnO₂
Battery-grade quality — low impurity profile, suitable for alkaline & lithium MnO₂ cells.
Custom particle sizing — multiple mesh ranges and micron sizes to suit processing.
Full testing & COA — ICP-OES for heavy metals, moisture, loss on ignition.
Reliable supply chain — stable monthly capacity & export experience.
Flexible packaging & logistics — sea/air shipments, export documentation.
Mesh / Particle Size Guidance
Coarser (>100 µm / small mesh) suitable for pigments / some industrial uses.
Fine powders (sub-micron to few µm / high mesh like 200 mesh) often required for battery cathode mixing to ensure good dispersion and electrochemical performance.
Quality & Testing
We test every batch with ICP-OES for heavy metal contaminants, XRD for phase verification, particle size analysis (laser diffraction), moisture by Karl Fischer and LOI. A sample COA is available for download. For battery customers we can provide production-lot traceability and additional electrical performance tests on request.
Packaging, Storage & Shipping
Packaging options: 25 kg kraft bag (PE liner) / 500 kg FIBC / 1 MT jumbo. Custom labeling available.
Storage & handling: Store in cool, dry place. Keep bags sealed to avoid moisture uptake. For transport classify per local regulations and provide SDS.
Shipping tips: For bulk shipments declare HS code (you can place HS code on page once confirmed with your export team). For air shipments check IATA restrictions on chemical powders — coordinate with freight forwarder.
