COMPOSITE ELECTRODE MATERIAL, METHOD OF MANUFACTURING THE SAME, AND COMPOSITE ELECTRODE USING COMPOSITE ELECTRODE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a composite electrode material superior in high reversible capacity and filling characteristic, and suitably used as an electrode material for a lithium ion battery and an electrochemical super capacity. SOLUTION: In this composite electrode material prepared by coating a surface of a conductive material having an average particle size of primary particles of 10-60 nm, and a specific surface area by nitrogen adsorption of 50-300 m2 /g, with metallic oxide capable of absorbing and desorbing lithium, the conductive material is carbonaceous material, and the metallic oxide is the oxide of at least one kind of metal selected from the metals belonging to a range of the fourth to the sixth cycle and the groups 3 to 12 in the periodic table.
