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.

Process for the preparation of a porous carbon material using an improved amphiphilic species

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. for at least 15 min so as to obtain a porous carbonaceous material, which is then cooled so as to form the porous carbonaceous material having a modal pore size and a pore volume and a skeleton density.

A process for preparing a porous carbon material. The process comprises the process steps: providing a carbon source; providing an amphiphilic species; contacting the carbon source and the amphiphilic species to obtain a precursor; and heating the precursor to obtain the porous carbon material; wherein the carbon source comprises a carbon source compound, wherein the carbon source compound comprises an aromatic ring having one or more attached OH groups and an ester link.

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 &#x3bc;m and contain mesopores and macropores which form a three-dimensionally interconnected pore structure.
