正负极电解液对钒电池能量衰减的影响研究
Study on effect of cathode and anode electrolyte on energy attenuation of vanadium battery
摘要
Abstract
In order to improve the energy efficiency of vanadium battery and reduce the decay rate of battery during charge and discharge cycle,the charge and discharge experiments were performed on three different batteries,which had different components of cathode and anode vanadium electrolyte.Three groups of electrolytes of different composition with the concentration of vanadium was 1.7 mol/L,the concentration of sulfate was 4.5 mol/L,the concentration of vanadium was 1.55 mol/L,the concentration of sulfate was 4.1 mol/L,and the concentration of vanadium was 1.55 mol/L,the concentration of sulfate was 4.7 mol/L were determined by cyclic voltammetry.The results show that when the anode electrolyte has higher concentration of sulfuric acid and lower vanadium concentration,the vanadium ion migration quantity is less,the capacity fading is slower and the power-energy performance is better.关键词
