Patent ID: 7147970

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, granular graphite characterized by an average layer spacing (d 002 ) of at most 0.345 nm as measured by X-ray diffraction method and a specific surface area below 1 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 granular graphite 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 granular graphite), wherein the fine electroconductive additive is an electroconductive carbon black selected from the group consisting of acetylene black and furnace black.
