Abstract
Manganese phosphate is prepared by reacting pyrophosphoric acid with an oxide containing tetravalent manganese, trivalent manganese, or divalent manganese to obtain a manganese pyrophosphate complex solution, followed by decomplexation to obtain a manganese phosphate precipitate. A carbon-coated lithium manganese iron phosphate material is prepared using manganese phosphate as a lithium battery material.
Claims16
A method for preparing manganese phosphate, characterized in that the method comprises:
