Evaluation of the Lyophilicity of Activated Carbons for Supercapacitors

Abstract

Examination of the surface of activated charcoals and interface by measuring the integral heat of wetting, ζ-potential, and concentration of functional groups on the surface of activated carbons of various grades, used as electrode materials for supercapacitors, allows scientifically substantiated choice of supercapacitor electrode materials and electrolytes. A scientifically substantiated approach to choosing an electrode–electrolyte pair for a symmetrical supercapacitor with definite maximal capacitance or maximal pulse power is suggested.
