Abstract
Additive material for an electrode of an electrochemical cell, double-layer capacitor and production method for such an electrode. Known additive materials for an electrode of an electrochemical cell contain electrically conductive particles composed of carbon, such as e.g. conductive carbon blacks or graphites. To provide an additive material having comparatively high ionic conductivity starting therefrom, it is proposed that the carbon additive particles have an average particle diameter in the range of 1 to 20 μm and contain mesopores and macropores which form a three-dimensionally interconnected pore structure.
