Abstract: The present invention provides an electrochemical cell or battery, which has a nonmetal negative electrode (anode). That is, no solid metal active material is used in the cell. Rather than the conventional solid lithium metal anode, the active material of the new anode comprises a compound of vanadium oxide. Accordingly, the lithium cell of the invention comprises a positive electrode and a negative electrode, where the negative electrode comprises a compound of vanadium oxide which in a fully discharged state is represented by the nominal general formula V.sub.6 O.sub.13 or Li.sub.y V.sub.6 O.sub.13, y equal to 0; and, in a fully or partially lithiated, fully or partially charged state, is represented by the nominal general formula Li.sub.y V.sub.6 O.sub.13, where y is greater than 0 and less than or equal to 8. The unique negative electrode of the invention demonstrates exceptional performance without the disadvantages of metallic lithium negative electrodes.

Abstract: Increasing the percentage of the 3R phase present in graphite reduces the first capacity loss of anodes employing the so modified graphite. Conversion of 2H phase graphite to 3R phase graphite can be achieved by grinding graphite. Non-aqueous solid electrochemical cells with improved performance can be fabricated by employing intercalation based carbon anodes comprising graphite with high percentage of 3R. When employed in an electrochemical cell, the first cycle capacity loss of only about 10%.
