Na2SO4,CH3CH2OH and the mixture of them were used as the electrolyte additives of vanadium flow battery respectively.The effects of the additives on the electrolyte were studied by cyclic voltammetry (CV),charge-discharge technique and thermal performance test.The results indicate that the electrochemical activity and thermal stability of the electrolyte are improved by adding the mixture of Na2SO4 and CH3CH2OH.%分别采用硫酸钠、乙醇以及将二者混合的复合物质作为钒电池电解液的添加剂,采用循环伏安、充放电、紫外可见光测试、热稳定性测试等方法研究了不同添加剂对电解液的影响,结果表明,复合添加剂(硫酸钠和乙醇的混合物)可以有效改善钒电池正极电解液的电化学活性以及热稳定性.
