In the aprotic electrolyte they reach 150 F g−1 and 60 F cm−3.A detailed comparison of the capacitive behaviour of CDCs at high current density (up to 100 mA cm−2) with other microporous and mesoporous carbons indicates better rate capabilities for the present materials in both electrolytes. This is due to the high surface area, the accessible porosity and the relatively low oxygen content.It also appears that the surface-related capacitances of the present CDCs in the aprotic electrolyte are in line with other carbons and show no anomalous behaviour.Peer reviewedElsevier200920092008info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_650122195 bytesapplication/pdfhttp://hdl.handle.net/10261/11096reponame:DIGITAL.CSIC.
