Abstract
A conductive polymer material is provided that includes an electrically conducting monomer and a zwitterionic sulfate chemically attached to the monomer. The electrically conducting monomer is at least one of acetylene, pyrrole, thiophene, phenylenevinylene, paraphenylene and aniline. The zwitterionic sulfonate includes an imidazolium group or an ammonium group. A solid-state battery is also provided that includes the conductive polymer material in an electrode. The solid-state battery includes an anode, a cathode and a solid electrolyte disposed between the anode and the cathode. At least one of the anode and the cathode includes the conductive polymer material.
