The paper discusses the impact of the aqueous electrolytes on the electrochemical capacitor capacitance using two activated carbons (CA and Norit GSX) and carbon nanotubes. The activated carbon CA (2300 m2/g) showed best electrochemical performance in 1M Na 2SO3 , despite the considerably lower conductivity of the electrolyte in comparison to 1M H2 SO4 and 6M KOH. This dependency was not observed for the commercial activated carbon and carbon nanotubes. This may prove that carbon CA possesses the most suitable pore structure to this type of electrolyte.
