Patent ID: 8617736

Claim:
A flexible electrode comprising: a fabric substrate; a first conductive polymer selected from the group consisting of polypvrroles, polyamilines, polyphenyl mercaptans, polycarbazoles, polyindoles, polyfurans, polyoxyphenazines, polypyridines, polypyrimidines, polyquinolines, polybenzimidazoles and polyanthraquinones; a second conductive polymer which is different to the first conductive polymer and is selected from the polythiophene class; and a counterion stable to lithium, wherein either: (a) the first conductive polymer and the second conductive polymer are in the form of a mixture of conductive polymers on the fabric substrate, (b) the first conductive polymer and second conductive polymer are present as separate lavers on the fabric substrate, or (c) the first conductive polymer and the second conductive polymer ace in the form of a copolymer on the fabric substrate.
