Electrode material for non-aqueous solvent secondary cell, electrode and secondary cell |
摘要 |
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 secondary cell which has large charge-discharge capacities, a small irreversible capacity determined as a difference between the doping capacity and the de-doping capacity, and also excellent cycle characteristics. |
