Influence of Conductive Dopants on Properties of Nanostructured Carbon-Based Electrochemical Capacitors

Abstract

The specific energy parameters of nanostructured electrode materials of electrochemical capacitors obtained by the method of multistage calendering are studied in this work. The dependence of electrical conductivity; the specific capacity of an electrical double layer of electrodes; and the internal resistance of electrochemical capacitors on the nature, quantity, and spatial localization (in the volume of the active layer and/or at the active layer–current collector interface) of conductive dopants (carbon black and grown in vacuum carbon fibers) are examined.
