ABSTRACT:
A lithium battery essentially consisting of an amorphous cathode active material mainly composed of V.sub.2 O.sub.5 and prepared by adding with at least one first additive selected from the group consisting of P.sub.2 O.sub.5, TeO.sub.2, GeO.sub.2, Sb.sub.2 O.sub.3, Bi.sub.2 O.sub.3 and B.sub.2 O.sub.3 and/or at least one second additive selected from the group consisting of MoO.sub.3 and WO.sub.3, heating to melt the admixture and then quenching the molten admixture; an anode active material made of metallic lithium or a lithium alloy; and an electrolyte made of a mixture of a aprotic solvent and a lithium salt. The battery is a small-sized and light-weight secondary battery having a high energy density and being improved in charge-discharge cycle lifetime.
