Abstract: Known processes for preparing a porous carbonaceous material require lengthy polymerization and washing steps involving solvents or neutralizing agents. The use of high quantities of pore formers leads to a lower carbon yield and higher costs, and use of sulphuric acid leads to sulphur contamination of the final material, but also to corrosion and corrosive by-products and a more complicated handling of the process. In order allows the manufacturing of a porous carbonaceous material with a high pore volume and avoiding the disadvantages of the known methods, a process is provide that comprise the steps of a) providing at least one carbon source and at least one amphiphilic species, b) combining at least the carbon source and the amphiphilic species to obtain a precursor material, c) heating the precursor material to a temperature in the range between 300° C. and 600° C.

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 ?m and contain mesopores and macropores which form a three-dimensionally interconnected pore structure.
