ABSTRACT:
An electrolyte for a Redox flow battery contains from 1 to 4 normal hydrochloric acid and at least 0.5 mole/liter of an active material, and further contains from 0.1 to 4 normalities of an acid comprising an anion which does not inhibit the electrode reactions in addition to the hydrochloric acid. This electrolyte reduces the cell resistivity and improves the solubility of active materials.
