Polyfurfuryl alcohol derived activated carbons for high power electrical doub…
a b s t r a c t Polyfurfuryl alcohol (PFA) derived activated carbons were prepared by the acid catalysed polymerization of furfuryl alcohol, followed by potassium hydroxide activation. Activated carbons with apparent BET surface areas ranging from 1070 to 2600m2 g−1, and corresponding average micropore sizes between 0.6 and 1.6nm were obtained. The porosity of these carbons can be careful…

An activated carbon monolith as an electrode material for supercapacitors
A B S T R A C T Activated carbon binderless monoliths with high consistency and large porosity, synthesised from a mesophase pitch, are studied as electrodes for supercapacitors. The electrochemical cells prepared provided high capacitance values in sulphuric acid media (334 F g-1) and very low electrical resistivity, which results in a very efficient energy storage device (12 Wh Kg-1 maximu…

Effects of thermal treatment of activated carbon on the electrochemical behav…
Abstract This paper studies the electrochemical behaviour of activated carbons with different oxygen content and investigates the contribution of pseudocapacitance to the global behaviour of the samples. A mesophase-derived activated carbon was further heat treated to 600 or 1000 ◦C in nitrogen. The changes in texture and surface chemistry induced by the thermal treatment were deeply studied…

A study of Faradaic phenomena in activated carbon by means of macroelectrodes…
a b s t r a c t The electrochemical behaviour of a chemically activated carbon with oxygen-containing surface groups was studied using a conventional macroelectrode configuration with disc electrodes and the single particle microelectrode technique. The results of both experimental set-ups were compare taking into account the visible peaks of the surface groups, capacitance and Faradaic curr…

Long-term cycling of carbon-based supercapacitors in aqueous media
a b s t r a c t The behaviour of mesophase-derived electrodes on long-duration cycling conditions was studied in 1M sulfuric acid and 6M potassium hydroxide. Variation in the specific capacitance values with the number of cycles shows a good cycling life performance in acidic media but very poor in an alkaline electrolyte. The total loss of capacitance after 7000 cycles in acidic media is 8…
