Disclosed is an electrode comprising a polymeric material containing or being composed of subunits according to general formulae (I) and (II) wherein in these structures (I) and (II) n is an integer not smaller than 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-), R 1 , R 2 , R 3 and R 4 each independently represent H, alkyl (preferably - CH 3 , -C 2 H 5 ), alkoxy-(preferably -OCH 3 , -OC 2 H 5 ), -halogen or -CN, Ar 1 and Ar 4 independently represent a bridging aryl group, Ar 2 and Ar 3 independently represent a non-bridging aryl group, and R 5 is a bridging alkyl, alkene or aryl group. Further, a Lithium-ion battery and a supercapacitor with such an electrode and the use of said polymeric material as electrode active material in the electrode of a battery or in the electrode of a supercapacitor and/or as an electrode binder is disclosed. |
