The method is based on a sol-gel process starting with carbonized resorcinol-formaldehyde resins containing an electrochemically active form of ruthenium oxide. A speciﬁc capacitance of 256 F/g is observed for a carbon xerogel containing 14 wt.% Ru, which corresponds to more than 50% utilization of the ruthenium.
