Patent ID: 7052804

Claim:
A positive electrode for incorporation into an electrochemical cell comprising a negative electrode of an anode material capable of intercalating and de-intercalating an alkali metal, the positive electrode comprising: a) a cathode active material contacted to one major side of a current collector with a sacrificial structure of the alkali metal contacted to the other major side thereof, wherein the cathode active material is selected from the group consisting of V 2 O 5 , V 6 O 13 , SVO, CSVO, MnO 2 , TiS 2 , MoS 2 , NbSe 3 , CuO 2 , Cu 2 S, FeS, FeS 2 , Ag 2 O, Ag 2 O 2 , CuF, Ag 2 CrO 4 , copper oxide, copper vanadium oxide, polypyrroles, polythiophenes, polysulfides, polyanilines, polyacetylenes, and mixtures thereof; b) wherein the positive electrode is positionable opposite the negative electrode with a separator provided intermediate the negative and positive electrodes to prevent direct physical contact between them; and c) wherein the negative and positive electrodes are activatable with an electrolyte to cause the sacrificial structure of alkali metal to be completely consumed in the cathode active material to thereby provide the electrocheinical cell.
