Manganese Dioxide

Description

Product Overview
Manganese Dioxide (MnO₂) is a high-purity inorganic compound essential for lithium battery cathode manufacturing, water treatment catalysis, and specialty glass production. Its key value proposition lies in delivering consistent electrochemical activity and oxidation efficiency, directly impacting end-product performance and operational yield. Strategically, securing a reliable MnO₂ supply mitigates production volatility in the fast-growing energy storage and environmental remediation markets.

Key Specifications & Technical Characteristics

• Chemical composition: Manganese Dioxide (MnO₂), natural or electrolytic (EMD) grade

• Purity level: 91%–99.7% (depending on industrial grade; battery-grade ≥99.5%)

• Physical characteristics: Black or dark-brown powder; typical particle size D50 5–25 µm; tap density 2.0–3.2 g/cm³

• Packaging options: 25 kg multi-layer paper/plastic bags, 500 kg–1,000 kg jumbo bags, or customer-specified bulk containers

• Shelf life: 24 months in dry, sealed conditions away from reducing agents

Core Industrial Applications

• Lithium-ion batteries (primary Li/MnO₂ cells): Provides high energy density and stable voltage, outperforming lower-purity oxides through reduced self-discharge and extended shelf life.

• Water treatment & catalysis: Removes iron, manganese, and hydrogen sulfide in filtration systems; delivers faster reaction kinetics and lower sludge volume compared to alternative oxidants.

• Glass & ceramics manufacturing: Acts as a decolorizing agent (counteracting iron impurities) and colorant; superior particle uniformity minimizes streaking and rejects.

Competitive Advantages

• Quality consistency: Lot-to-lot purity variation <0.5%, backed by ISO 9001:2025 certified batch testing.

• Supply reliability: Dual-sourced raw material streams with 50,000 MT annual capacity and strategic warehousing on three continents.

• Logistics capability: Direct FOB/CIF shipment from major ports; average lead time 14–21 days.

• Price competitiveness: Long-term mining partnerships enable stable quarterly pricing, reducing buyer’s input cost volatility.

• Environmental compliance: Zero liquid discharge processing; full REACH and RoHS documentation available.

Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT

• Loading capacity: 20–25 MT per 20-foot dry container
