Abstract [en]

The effect of nanostructured carbon and porosity on the interfacial processes was investigated. Fast cyclic voltammetry (CV) with a large number of cycles was performed at different sweep rates to elucidate interfacial processes occurring at different time scales. The electrochemical impedance spectroscopy (EIS) was performed both before and after the CV experiments of the material. The CV curves show linear current-potential relationship at high sweep rates, which indicates a distributed resistance and capacitance in response to fast charging and discharging due to porous structure.
