Patent number: 8142918Abstract: This disclosure relates to methods of making a cathode for a lithium battery. The batteries include: (a) treating a cathode current collector with flame or corona; (b) coating a slurry containing iron disulfide, a first solvent, and a binder onto the cathode current collector obtained from step (a) to form a coated cathode current collector, in which the slurry contains about 73-75% by weight solids and the binder contains 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, in which the cathode contains no more than 0.Type: GrantFiled: June 1, 2011Date of Patent: March 27, 2012Assignee: The Gillette CompanyInventors: Christopher Boczer, Frank M.
