Purpose: Use of ultrasonic radiation for improving the properties of activated carbon was the aim of this paper. Increase of density of states at Fermi level was the main factor, responsible for working characteristics of electrochemical supercapacitors. Design/methodology/approach: Working parameters of supercapacitors on the base of activated carbon have been studied by means of precisional porometry,...
The relation between the porous structure and the electron structure in carbon materials was investigated in order to optimize the effiency of the physical-chemical processes in an electric double layer (EDL) formed at the boundary between the carbon material and the electrolyte (KOH 30 % aqueous solution). In particular, an Ni2+ intercalative modification of nanoporous carbon resulted in more than...
