Important issue regarding the EDL capacitance is the pore size in carbon electrodes. It is known that SiC and TiC derived carbon materials, which average pore size ranges between 0.7 and 0.9 nm, possess the highest energy density among all porous carbons. The size of nanopores is especially critical for the negatively charged carbon electrode, because the cations of the common organic electrolytes, such as tetraalkyl ammonium salts, are roughly of the same size (~0.7 nm). It is likely that part of the nanopores are too small to fit cations, or even worse – the nanopores capture the ions from the elec-trolyte. Post-activation of carbide-derived carbon (CDC) in oxidative environment was investigated to enhance the adsorption/desorption characteristics and mobility of ions in nanoporous CDC electrodes produced by Skeleton Technologies.
