Abstract (en)
[origin: WO0243088A2] The invention concerns a method for preparing activated carbons based on wood, preferably softwood and in particular pine wood, for making electrodes for energy storage cells, particularly for super-capacitors. Said activated carbons have a volume of mesopores less than 75 % of the total pore volume and a volume of micropores less than 57 % of the total pore volume. The invention also concerns a method for making an electrode for energy storage cell, comprising the application of such an activated carbon on a support, preferably by coating derived from a slurry. The energy storage cells using said activated carbons advantageously provide a better compromise between energy density and power density.
