Manganese Dioxide (MnO2) Powder, Battery Grade (>=90-92%, 3 um)

Cat No:BMSPEM-0398

Description

This battery-grade manganese dioxide (MnO2) powder from Eata Battery is a high-purity, fine-particle cathode active material for primary batteries and battery-related research, supplied as a free-flowing powder in 500 g sealed bags. Specifications: MnO2 content >= 90-92.0%; H2O <= 3.0%; Fe <= 100 ppm; Cu, Pb, Ni, Co and K each <= 5 ppm; pH 5.5-7.5 (distilled water method); sulfate <= 1.3%; hydrochloric acid insoluble matter <= 0.05%; mean particle size 3 um. The tightly controlled metallic impurity profile reduces self-discharge and shelf-life losses caused by impurity-catalyzed electrolyte decomposition, and the near-neutral pH keeps the powder compatible with both PVDF-NMP and aqueous CMC/SBR binder systems. With a 3 um mean particle size it can be used directly for thick-film or slurry-cast electrodes without additional grinding, and it serves as the active cathode material in primary Li-MnO2 cells and as a host electrode for reversible Zn2+ insertion in rechargeable aqueous zinc-ion batteries.
