Abstract
An electrode material for a lithium ion battery including an active material represented by LiMPO4 (M is at least one selected from the group consisting of Fe, Mn, Co, Ni, Zn, Al, Ga, Mg, and Ca), in which an oil absorption amount for which diethyl carbonate is used (DEC oil absorption amount) is 50 cc/100 g or more and 80 cc/100 g or less, and a ratio (DEC/NMP) of the DEC oil absorption amount to an oil absorption amount for which N-methyl-2-pyrrolidinone is used (NMP oil absorption amount) is 1.3 or more and 1.8 or less.
Claims6
