NEW ELECTROLYTES AND POLYMER CATHODE MATERIALS FOR LITHIUM BATTERIES

Novel aprotic electrolytes, based on propylene carbonate and gamma-but yrolactone compositions with a variety of added organic compounds (pol yethers, quinones, aromatic hydrocarbons) have been devised. The elect rolytes configured have been shown to be able to form protective, ion- conductive films on the surface of lithium and to improve dramatically the operational characteristics of lithium chemical cells. Processes for synthesizing novel composites, based on conducting organic polymer s (polyaniline, polypyrrole, etc.) and transition metal (V2O5, TiS2) b inary compounds-challenging cathode materials for secondary lithium ba tteries have been developed.
