研究了甘油和正丙醇作为钒液流电池(VRFB)电解液的添加剂。采用循环伏安法、交流阻抗谱和计时电流法研究了添加剂对VRBF正极电解液电化学性能的影响。结果表明，甘油的加入改善了电极的电化学性能。这归因于钒离子在电极表面的更有效吸附，而这又是由于电解液中羟基的活性增加所致。©2012电化学会。[DOI：10.1149/2.091206jes]版权所有。
Glycerin and n-propyl alcohol have been investigated as electrolyte additives for vanadium redox flow batteries (VRFB). The effects of these additives on the electrochemical performances of VRBF positive electrolyte were investigated by cyclic voltammetry, electrochemical impedance spectroscopy and chronoamperometry. The results show an improved electrochemical performance upon the addition of glycerin. This is attributed to more effective adsorption of vanadium ions at the electrode surface, which, in turn, is due to the increased activity of the hydroxyl groups in the electrolyte. © 2012 The Electrochemical Society.
