Ultrasonic modification of electrode materials of supercapacitors

Abstract

Electrode materials based on birch charcoal (BC) and flax fibers (FF) and nanocarbon (NC) were stu  died using impedance spectroscopy and galvanostatic charge-discharge methods. It was proved that ultrasonic treatment promotes more increase in specific capacity of BC and FF than of NС. The shifts of the Fermi level of ultrasonic modificated materials were obtained from the volt-farad depen  dencies.
