Abstract:
A method and systems are provided for utilizing black powder to form an electrolyte for a flow battery. In an exemplary method the black powder is heated under an inert atmosphere to form Fe3O4. The Fe3O4 is dissolved in an acid solution to form an electrolyte solution. A ratio of iron (II) to iron (III) is adjusted by a redox process.
