Patent ID: 7235329

Claim:
An electrode material for a non-aqueous solvent secondary cell, comprising a non-heated powdery mixture of a metal material capable of doping and dedoping lithium, a non-graphitic porous carbon material characterized by an average layer spacing (d 002 ) of at least 0.365 nm as measured by X-ray diffraction method and a specific surface area of at least 2.0 m 2 /g as measured by BET method according to nitrogen adsorption and a fine electroconductive additive; and containing the metal material at 5-60 wt. %, the non-graphitic porous carbon material at 40-95 wt. % (giving a total of 100 wt. % together with the metal material), and the fine electroconductive additive at 1-10 wt. % (based on the total of the metal material and the non-graphitic carbon material) wherein said metal material comprises a simple substance of an element selected from the group consisting of an A-group consisting of Ag, B, Al, Ga, ln, Tl, Si, Ge, Sn, Pb, Sb, Bi and Te; or an intermetallic compound comprising at least one element selected from the group consisting of said A-group and a metal element selected from B-group consisting of Cu, Mg, Mo, Fe, Ni and Co.
