Abstract
The invention relates to electrochemical energy storage devices containing a composition comprising an electrically conductive polymer based on polypyrrole, substituted or otherwise, and ionic groups which comprise an R-sulphate or R-sulphonate group, R denoting an alkyl or aryl radical. The invention also relates to the use of these devices as a supercapacitor or as a rechargeable generator.
