Cyclic voltammetry(CV) results indicated that electrode process of the V( Ⅳ )/V( Ⅴ ) couple was electrochemically quasi-reversible with a rate constant of 8 × 10^-4 cm/S . Increasing concentration of sulfuric acid was electrochemically favourable for the V( Ⅳ )/V( Ⅴ )couple while elevated temperature was unfavourable for this system. Constant-current electrolysis results showed that current efficiency of more than 95 % could be achieved, which indicated that the V( Ⅳ )/V( Ⅴ ) couple had excellent electrolytic performance and was suitable for the application as the anolyte of redox flow batteries.展开更多
