A cathode for a lithium battery is described. The cathode includes: (a) a
current collector including aluminum foil; and (b) an active cathode
material including: (i) manganese dioxide; (ii) conductive materials; and
(iii) a binder selected from the group consisting of linear di- and
tri-block polymers, linear tri-block polymers 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 polyvinylidine fluoride
homopolymers.
