A battery having a positive electrode comprising delta LixV2O5, wherein x ranges from 0.9 to 1.0, wherein the LixV2O5 has admixed therewith a conductive material. The delta LixV2O5 may be formed chemically by reacting V2O5 with a lithium salt to transform all of the V2O5 into LixV2O5. Alternatively, and preferred is to form it by electrochemically reacting an admixture of V2O5 and a lithium metal containing electrode in an electrochemical reactor cell having a lithium containing electrolyte in a non-aqueous solvent to transform all of the V2O5 into LixV2O5, after which the LixV2O5 is removed from the cell and used as a predetermined electrode configuration for use in a lithium metal free secondary cell. The positive electrode is delta LiV2O5 with a conductive material therewith. The delta form of LiV2O5 of this invention has its three strongest X-ray diffraction peaks at 4.97, 3.25 and 3.39 in order of decreasing intensity. |
