Patent ID: 7967875

Claim:
A method of making a lithium battery, the method comprising: (a) coating a slurry comprising iron disulfide, a solvent selected from the group consisting of hydrocarbons and paraffinic solvents, and a binder onto the cathode current collector to form a coated cathode current collector, wherein the binder comprises a polymer selected from the group consisting of linear di- and tri-block copolymers, linear tri-block copolymers cross-linked with melamine resin, ethylene-propylene copolymers, ethylene-propylene-diene terpolymers, tri-block fluorinated thermoplastics, hydrogenated nitrile rubbers, fluoro-ethylene-vinyl ether copolymers, thermoplastic polyurethanes, thermoplastic olefins, and polyvinylidene fluoride homopolymers; (b) drying the coated cathode current collector obtained from step (a) to provide a cathode, wherein the cathode comprises no more than 0.5% by volume of the solvent; and (c) incorporating the cathode obtained from step (b), an anode comprising lithium, and an electrolyte comprising dimethyloxyethane, dioxolane, and lithium iodide into a housing to form the lithium battery.
