Abstract
An electrode material for a lithium-ion secondary battery of the present invention includes particles which are made of LiFeMnMgCaAPO, 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 LiFeMnMgCaAPOand lattice constants b2 and c2 of FeMnMgCaAPOobtained by deintercalating Li from LiFeMnMgCaAPOby means of an oxidation treatment using nitrosonium tetrafluoroborate in acetonitrile is 1.32% or more and 1.85% or less.
