  • Patent number: 10388958
    Abstract: An electrode for an electrochemical element with an organic electrolyte includes a polymeric material containing or composed of subunits according to general formulae (I) and/or (II): wherein n is an integer ?2, Y represents an amide group (—NH—CO— or —CO—NH—), an ester group (—O—CO— or —CO—O—) or a urethane group (—NH—CO—O— or —O—CO—NH—), R1, R2, R3 and R4 each independently represent H, alkyl (preferably —CH3, —C2H5), Alkoxy-(preferably —OCH3, —OC2H5), -halogen or —CN, Ar1 and Ar4 independently represent a bridging aryl group, Ar2 and Ar3 independently represent a non-bridging aryl group, and R5 is a bridging alkyl, alkene or aryl group, wherein Ar1 and Ar4 in structures (I) and (II) independently represent a bridging aryl group.
