Abstract
An improved rechargeable lithium battery is described comprising a transition metal compound as cathode active material and carbonaceous particles as anode active material, having prior intercalated lithium ions in the carbonaceous particles in the anode of the assembled lithium battery, thereby reducing the weight of the cathode active material required. The rechargeable lithium battery has increased energy density per unit weight and per unit volume.
