    摘要： This disclosure relates to methods of making a cathode for a lithium batter. The methods 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 0.5% by volume of the first solvent and is capable of being bent to 180°. This disclosure also relates to methods of making a lithium battery.

    摘要： A primary cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which contains an additive, preferably iodine, suppressing voltage delay. A cathode slurry is prepared comprising iron disulfide powder, carbon, binder, and liquid solvent. The mixture is coated onto a conductive substrate and solvent evaporated leaving a dry cathode coating on the substrate. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.
