摘要：
An electrode material for a lithium-ion secondary battery of the present invention includes particles which are made of LiFe x Mn 1-w-x-y-z Mg y Ca z A w PO 4 , 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 LiFe x Mn 1-w-x-y-z Mg y Ca z A w PO 4 and lattice constants b2 and c2 of Fe x Mn 1-w-x-y-z Mg y Ca z A w PO 4 obtained by deintercalating Li from LiFe x Mn 1-w-x-y-z Mg y Ca z A w PO 4 by means of an oxidation treatment using nitrosonium tetrafluoroborate in acetonitrile is 1.32% or more and 1.85% or less.
