Abstract: A process for the preparation of a porous carbon material using an improved amphiphilic species. Also disclosed are a porous carbon material, devices comprising the porous carbon material and use of an amphiphilic compound for the preparation of a porous carbon material. The process for preparing a porous carbon material comprises the process steps: (a) providing a carbon source comprising a first carbon source compound; (b) providing an amphiphilic species comprising a first amphiphilic compound, the first amphiphilic compound comprising two or more adjacent ethylene oxide-based repeating units; (c) contacting the carbon source and the amphiphilic species to obtain a precursor; and (d) heating the precursor to obtain the porous carbon material.

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.
