Abstract

See full text

A method of producing lithium iron phosphate includes adding iron particles containing 0.5 mass % or more of oxygen to an aqueous solution containing a phosphoric acid, a carboxylic acid and a lithium source, and causing components contained in the aqueous solution and the iron particles to react with each other under an oxidizing atmosphere and thereby form a reaction liquid; drying the reaction liquid to form a lithium iron phosphate precursor; and baking the lithium iron phosphate precursor under a non-oxidizing atmosphere to obtain the lithium iron phosphate.
