Ionic and Electronic Conducting Binder for Electrochemical Devices

摘要

An ion conducting and electron conducting polymer is comprised of a first polymer of a single-sulfonic acid polymer or a multi-sulfonic acid polymer and a second polymer of an EDOT analog monomer having the following formula:; ;wherein z=O or S;; ;Y₂=—COH, —C₆H₁₃, or —COOH; a=0 or 1; Y₃=—CH₃, —C₂H₅, —CH₂C₆H₆, —C₆H₁₃, —C₈H₁₇, —CH₂OC₆H₁₃, or —CH₂OC₆H₆; and b=0 or 1; wherein a sulfonic acid group of each branch of the first polymer electronically interacts with one or more thiophene rings of the second polymer; and wherein any remaining sulfonic acid groups on each branch of the first polymer are converted to SO₃Li.
