- •
The V(V) electrolytes with the addition of organic amines CTS, SA and NPAM and inorganic ammonium ATC, FAS and AFS remained stable from − 5 °C to 45 °C.
- •
The electrochemical activity for V(V) electrolytes with the addition of CTS, ATC, AFS and FAS was improved compared with the pristine one.
- •
Overall, the effect of the organic amines on the V(V) solution was better than the inorganic ammoniums.
- •
The VRB with CTS performed well with an energy efficiency of more than 80% and good cycling stability at a current density of 50 mAcm− 2.
