Battery Grade Manganese Sulfate Monohydrate
Molecular Formula:
MnSO4·H2O
CAS#.: 10034-96-5
Molecular Weight: 169.0159
Application:Battery grade manganese sulfate monohydrate powder is mainly used to prepare the precursor of lithium battery cathode ternary material (lithium nickel cobalt manganate). Manganese elements can improve the safety and stability of battery materials, and replace part of the cobalt content in the materials for reducing costs. Ca, Mg, Na and other impurities in manganese sulfate have an important impact on the high-temperature morphology and cycling performance of lithium-ion batteries, so manganese sulfate monohydrate used in power batteries requires very strict impurities content, and the number and scope of indicators are different from ordinary industrial and feed-grade manganese sulfate.
