Abstract

In this paper,cyclic voltammetry has been used to study the electrochemical performance of the treated and untreated graphite,soft graphite and PAN-carbon cloth in vanadium sulfate solution.The results show that: the reversibility of reaction can be improved on the surface of treated electrode,and the current can also increase;the electrochemical performance of treated electrode is remarkably enhanced;in the process of charge/discharge,the charge current can reach up to 20 mA/cm~(2),and discharge current up to 15 mA/cm~(2);surface morphology of the treated and untreated graphite show that the treatment can change the surface structure of electrode and also add the reaction area.
