Abstract
Abstract An anhydrous cell comprises an anode, a cathode, electrolyte and anhydrous solvent, the cathode comprising a mixture of polyacetylene powder and an electrically conductive material and the anode being an inorganic intercalating anode. Suitable materials for the anode include tungsten dioxide, titanium disulfide, vanadium diselenide and vanadium disulfide.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
A substantially anhydrous cell comprising (a) a cathode which comprises a mixture of polyacetylene powder and an electrically conductive material, (b) an organic solvent, (c) an electrolyte comprising a salt which is soluble in said solvent and (d) an inorganic intercalating anode, said cathode being insoluble in said solvent when said cathode is either undoped or p-doped, said solvent being stable to electrochemical decomposition and the anions of said salt being capable of p-doping said polyacetylene when an external electrical power source is supplied to said cell.
Claim 2
Dependent Claim
87 words
A substantially anhydrous cell comprising (a) a cathode which comprises a mixture of polyacetylene powder and an electrically conductive material, (b) an organic solvent, (c) an electrolyte comprising a salt which is soluble in said solvent and (d) an inorganic intercalating anode, said cathode being insoluble in said solvent when said cathode is either undoped or p-doped, said solvent being stable to electrochemical decomposition and the anions of said salt being capable of p-doping said polyacetylene when an external electrical power source is supplied to said cell.
