添加剂对全钒液流电池电解液稳定性的影响
Effects of additives on stability of anolyte for vanadium redox flow battery
摘要
Abstract
Potassium sulfate,sodium sulfate,zinc sulfate,urea,citric acid,sodium citrate,Trisodium citrate and EDTA were added to vanadium ion-H2SO4 solution and stored at a constant temperature of 43 ℃,and the solution was used as the anolyte with a higher concentration and more stable for vanadium redox batteny.Vanadium ion-H2SO4 solution stored at a constant temperature for 1 d and 30 d,and potentiometric titration was utilized to determine the concentration of vanadium ion.The results show that vanadium ion-H~O4 solution containing additives of potassium sulfate,sodium sulfate,zinc sulfate and urea was more stable compared with that without additives,but citric acid,sodium citrate,Trisodium citrate and EDTA are not suitable additives.关键词
