Cathode including transition metal/matrix polymer composition and a secondary polymer battery therefrom

A secondary polymer battery which comprises:

• a) a cathode containing a current collector made of an electrically conductive substrate and a composition placed on said current collector, said composition comprising:
• at least one of a transition metal salt of the formula MXn, wherein M is a transition metal selected from the group consisting of Fe, Ni, Co, Cr, V, Mo and W, X is chlorine(Cl), and n is an integral number between 1 to 6;
• a matrix polymer which has a basic functional group with affinity for the transition metal species, and said group is selected from
• (i) the group consisting of halogen, nitrile, carboalkoxy, carbohydroxy, pyrrolidonyl and pyridinyl functional groups;
• (ii) the group consisting of ether, imine, sulfide and sulfone functional group;
• and
• (iii) the group consisting of polyaniline, polypyrrole and polythiophene;
• b) a polymer electrolyte containing a lithium salt;
• and
• c) an anode including a material selected from the group consisting of a lithium metal, a lithium alloy and a lithium intercalation material.
