Abstract

See full text

An electrode material for a lithium-ion secondary battery of the present invention includes particles which are made of LiFexMn1-w-x-y-zMgyCazAwPO4, have an orthorhombic crystal structure, and have a space group of Pmna, in which a mis-fit value [(1−(b2×c2)/(b1×c1))×100] of a bc plane which is computed from lattice constants b1 and c1 of the LiFexMn1-w-x-y-zMgyCazAwPO4 and lattice constants b2 and c2 of FexMn1-w-x-y-zMgyCazAwPO4 obtained by deintercalating Li from LiFexMn1-w-x-y-zMgyCazAwPO4 by means of an oxidation treatment using nitrosonium tetrafluoroborate in acetonitrile is 1.32% or more and 1.85% or less.
