Lean manganese carbonate ores are used as raw material, and the suspension electrolysis is used to improve the surface properties of solid phase; highly efficient additives are used to remove metal impurities such as molybdenum and iron to produce electrolytic manganese dioxide for mercury-free alkaline zinc-manganese batteries. Our products feature high purity and apparent gravity, with the liquid absorption more suitable for the technical requirements of alkaline zinc-manganese batteries. Our batteries feature small internal resistance, excellent continuous discharge performance of large current, and enhanced high-voltage discharge capacity. With sound forming of battery cathode, our products can meet the process requirements of alkaline zinc-manganese batteries. Used by battery manufacturers, our products boast preeminent performance, no matter in heavy load or light load discharging batteries.
Main applications: raw materials of mercury-free alkaline manganese batteries.

Manganese oxide is used as a raw material to produce high-purity manganese sulfate solution, and electrolyzed to generate crude products of electrolytic manganese dioxide. Then crude products go through pulverization, neutralization and physical treatment to produce final products. Our products feature high chemical purity, high tap density, more reasonable grain fineness distribution and better circulative discharge performance.
Main applications:material of anode of lithium batteries.
