An electrode material comprising a powdery mixture of a metal material (particularly, an intermetallic compound) and a capacitive carbon material each capable of doping and dedoping lithium, and an optionally added fine electroconductive additive, and containing the metal material and the capacitive carbon material in amounts of 5-60 wt. % and 40-95 wt. %, respectively, is used as an active substance for an electrode, particularly a negative electrode, of a non-aqueous solvent secondary cell. As a result, there is provided a non-aqueous solvent secondar...
The invention claimed is: 1. 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 (d002) of at most 0.345 nm as measured by X-ray diffraction method and a specific surface area below 1 m2 /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 to...
