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

In this work, a comparative study was done to determine the effects oftetrahydrofuran and dimethyl sulfoxide on the electrochemical behaviors of avanadium redox flow battery’s (VRFB’s) positive electrolyte. In this concept, cyclicvoltammetry and electrochemical impedance spectroscopy were used for thecharacterization of electrolytes consisting of additives, V(IV) and sulfuric acid.Currents and capacities of peaks were determined in cyclic voltammograms. Theredox reaction were controlled by diffusion and diffusion+adsorption intetrahydrofuran and dimethyl sulfoxide including positive electrolyte solutions ofVRFB, respectively. Resistance values were investigated in electrochemicalimpedimetric analysis. The morphological characterization of the pencil graphiteelectrodes used in cyclic voltammetric analysis, were done by scanning electronmicroscopic analysis.
