Abstract
An electrode material includes an inorganic particle and a carbonaceous film coating a surface of the inorganic particle, in which an amount of carbon is 0.8 to 2.5% by mass, and volume of micropores in a micropore diameter range of 2 to 200 nm is 3×10to 3×10cm/g. A method for manufacturing an electrode material includes a step of immersing the inorganic particle in an aqueous solution, a step of producing a slurry including the inorganic particle immersed in an aqueous solution, a carbonaceous film precursor, and water, a step of producing a dried substance of the slurry, and a step of calcinating the dried substance in a non-oxidative atmosphere, in which an amount of the carbonaceous film precursor blended into the inorganic particle is 1.0 to 5.0 parts by mass. A lithium-ion secondary battery includes a cathode that is the electrode; an anode; and a non-aqueous electrolyte.
