Patent ID: 8734988

Claim:
A secondary lithium ion battery comprising: (a) a cathode comprised of a positive current collector and a positive active material layer disposed on the current collector, wherein the positive active material layer is comprised of a lithium-containing composite oxide containing, in addition to Li, at least one of Co, Ni and, Mn; (b) an anode comprised of a negative current collector comprised of aluminum, copper, nickel, iron, titanium or cobalt; an alloy comprising at least one of aluminum, copper, nickel, iron, titanium and cobalt; or copper or stainless steel, wherein said copper or said stainless steel is surface-coated with carbon, nickel, or titanium and a negative active material layer disposed on the negative current collector, wherein the negative active material layer is comprised of binder, electrically conductive material, and polythiocyanogen as an anode-active material, wherein polythiocyanogen is disposed on the negative current collector at a loading of from about 1 to about 10 mg/cm 2 ; (c) an electrolyte comprised of at least one lithium ion conducting salt dissolved in at least one organic carbonate; and, (d) a separator.
