The nature of the solvent introduced in the battery determines the solubility and stability of the vanadium species of the solution. Ionic liquids (ILs), either pure or mixed with other solvents, are a promising alternative to aqueous electrolytes. ILs are organic salts composed entirely of ions and possess a low melting point (<100 °C).
The utilization of mixed acid solutions as supporting electrolytes is another method to improve the solubility of vanadium ions in supporting electrolytes and extend the temperature range of VFB operation.45,49,66 Additionally, their use can improve the electric conductivity and electrochemical activity of electrolytes.
