Conducting polymer containing supercapacitor

摘要

Supercapacitor comprising a positive electrode, a negative electrode, both based on p-doped electron-conductive polymer, and an electrolyte, characterised in that it additionally comprises an electrochemical shuttle consisting of an organic compound soluble in the said electrolyte, in a proportion of at least 10<-3> mole per litre, whose redox potential lies in the noncapacitive region of the said electron-conductive polymer and which is reversibly reduced at the negative electrode and oxidised at the positive electrode if the potential of these electrodes allows it. Curve C1 in the figure illustrates the voltage variations during a cycle.
