Carbon electrodes with high pseudocapacitance for supercapacitors

Russian Journal of Electrochemistry. 2012. Vol. 48. No. 4. P. 424-433.

 Electrochemical properties of electrodes on the basis of CH900-20 activated carbon 
(AC) cloth were studied in concentrated H 2 SO 4 solutions in a wide range of potentials 
from− 0.8 to+ 1 V RHE. Cyclic voltammetric curves measured in two ranges of potentials 
were analyzed: in the reversibility range (from 0.1 to 0.9 V) and in the deep cathodic 
charging range (from− 0.8 to 1 V). Electric double layer (EDL) charging occurs in the 
reversibility range, while faradaic processes of hydrogen chemisorption and its ...
