Abstract

An electrode material includes inorganic particles of LiFeMnMPOand a carbonaceous film coating surfaces of the inorganic particles, and volume of micropores having micropore diameter of 2 to 10 nm is 3 to 11 cm/g. A method for manufacturing an electrode material includes immersing the inorganic particles in an aqueous solution having pH of 7.0 to 10.0; producing a slurry including the inorganic particles, a carbonaceous film precursor, and water; producing a dried substance of the slurry by drying the slurry; and calcinating the dried substance in a non-oxidative atmosphere of 500° C. to 1,000° C., and an amount of the carbonaceous film precursor blended into 100 parts by mass of the inorganic particles when converted to a carbon element is 1.0 to 5.0 parts by mass. An electrode includes the electrode material. A lithium-ion secondary battery includes a cathode; an anode; and a non-aqueous electrolyte, the cathode being the electrode.
