Patent ID: 7753968

Claim:
A method of making a cathode for a lithium battery, the method comprising: (a) treating a cathode current collector with flame or corona; (b) coating a slurry comprising iron disulfide, solvent, and a binder onto the cathode current collector obtained from step (a) to form a coated cathode current collector, wherein the slurry comprises about 73-75% by weight solids and 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; and (c) drying the coated cathode current collector obtained from step (b) to provide a cathode, wherein the cathode comprises no more than 0.5% by volume of the solvent and is capable of being bent to 180°.
