β¦ Synopsis
The increasing attention being given to supercapacitors is stimulated by the prospect of using such devices as secondary power sources in electric vehicle propulsion. The present study focuses on redox supercapacitors with electronically conducting polymers as electrode materials. Performance data of a symmetric supercapacitor based on p-doped poly(pyrrole), of an unsymmetric supercapacitor based on both p-doped poly(pyrrole) and poly(3-methylthiophene), and of a symmetric supercapacitor based on pand n-doped poly(dithieno[3,4-b : 3',4'-dlthiophene) are here compared.

The performance of a polymer redox supercapacitor based on poly(dithieno[3,4-b : 3',4'-d] thiophene) in liquid and in polymer gel electrolyte was tested for capacity, energy density, power density and self-discharge. The results are very promising and demonstrate the viability of a symmetric superca
The electrochemical behaviour of ferrocene was studied in different gel polymer electrolytes based on methyl, ethyl and 2-ethoxyethyl methacrylate and compared to the liquid aprotic solution (propylene carbonate). Voltammetric and chronoamperometric measurements on microelectrodes were conducted in
