Supercapacitors are an important component in the electric energy landscape with rapidly growing importance. Their energy density still does not meet growing expectations. For improvements optimization of already established materials as well as new materials in electrodes and in electrolyte (solutions) are required. To compensate or correct drawbacks and flaws of a given material – whether new or already established – combination with a second one, i.e. formation of a composite, is a helpful and popular option. Carbon in its many forms is an established supercapacitor electrode material with only limited charge storage capability; intrinsically conducting polymers show promising storage capabilities but limited stability and electronic conductivity. Adding carbons to these polymers has been a popular recipe rather early, but a systematic survey of these combinations with attention to the type of carbon, of polymer, of their relative fractions and the electrode architecture has indicated major room for improvements. This update presents representative examples, follows lines of reasoning and searches for conclusions from already available results. It ends with suggestions for further research and development.
