Abstract

See full text

A method of manufacturing a multicomponent lithium phosphate compound particle with an olivine structure of formula LiyM11-ZM2ZPO4, M1 is Fe, Mn or Co; Y satisfies 0.9≦Y≦1.2; M2 is Mn, Co, Mg, Ti or Al; and Z satisfies 0XM1PO4, M1 is Fe, Mn or Co, and X satisfies 0.9≦X≦1.2, and a precursor of a lithium M2 phosphate compound with an olivine structure of formula LiXM2PO4, M2 is Mn, Co, Mg, Ti or Al, and X satisfies 0.9≦X≦1.2, to form a mixture; and subjecting the mixture to heating in an inert atmosphere or a vacuum.
