Abstract
A rechargeable electrochemical cell comprising a body of aprotic, non-aqueous electrolyte, first and second electrodes in effective electrochemical contact with the electrolyte, the first electrode comprising positive active cathode materials such as a lithiated intercalation compound serving as the cathode and the second electrode comprising a modified carbon material formed of a graphite or carbon based materials, for example, having a hydrogenated fullerene material, such as hydrogenated C.sub.60 or C.sub.70, adsorbed thereon and serving as the anode; whereby they provide a lithium-ion cell having improved reversible energy storage characteristics and irreversible energy loss characteristics as compared with similar lithium-ion cells having carbon anodes that are not so-modified with hydrogenated fullerene material.
