Flexible cathodes

A battery, comprising:

• a housing;
• an anode in the housing;
• and
• a cathode in the housing,
• wherein the cathode comprises a cathode active material comprising iron disulfide and a binder selected from the group consisting of polyvinylidene fluoride homopolymers, linear tri-block copolymers cross-linked with melamine resin, ethylene-propylene-diene terpolymers, tri-block fluorinated thermoplastics, hydrogenated nitrile rubbers, fluoro-ethylene-vinyl ether copolymers, thermoplastic polyurethanes, and thermoplastic olefins.

A method of making a battery, the method comprising:

• combining a binder and a cathode active material comprising iron disulfide to form a cathode;
• and
• adding the cathode into a housing to form the battery,
• wherein the binder is selected from the group consisting of polyvinylidene fluoride homopolymers, linear tri-block copolymers cross-linked with melamine resin, ethylene-propylene-diene terpolymers, tri-block fluorinated thermoplastics, hydrogenated nitrile rubbers, fluoro-ethylene-vinyl ether copolymers, thermoplastic polyurethanes, and thermoplastic olefins.
