Piklerin akım ve kapasiteleri voltamogramlardan elde edilmiştir. Redoks reaksiyonu tetrahidrofuran içeren pozitif elektrolit çözeltisinde difüzyonken ile kontrollü gerçekleşmişken, dimetil sulfoksit içeren çözeltide difüzyon+adsorbsiyon ile kontrollü olarak gerçekleşmiştir. Elektrokimyasal impedimetrik analizlerde ise direnç değerleri incelenmiştir.

Investigation the Effects of Tetrahydrofuran and Dimethyl Sulfoxide on the Positive Electrolyte of Vanadium Redox Battery

Abstract

In this work, a comparative study was done to determine the effects of tetrahydrofuran and dimethyl sulfoxide on the electrochemical behaviors of a vanadium redox flow battery’s (VRFB’s) positive electrolyte. In this concept, cyclic voltammetry and electrochemical impedance spectroscopy were used for the characterization of electrolytes consisting of additives, V(IV) and sulfuric acid. Currents and capacities of peaks were determined in cyclic voltammograms. The redox reaction were controlled by diffusion and diffusion+adsorption in tetrahydrofuran and dimethyl sulfoxide including positive electrolyte solutions of VRFB, respectively. Resistance values were investigated in electrochemical impedimetric analysis. The morphological characterization of the pencil graphite electrodes used in cyclic voltammetric analysis, were done by scanning electron microscopic analysis.
