OverviewDesignHistoryEvaluationTraditional flow batteriesHybridOrganicOther typesA flow battery is a rechargeable fuel cell in which an electrolyte containing one or more dissolved electroactive elements flows through an electrochemical cell that reversibly converts chemical energy to electrical energy. Electroactive elements are "elements in solution that can take part in an electrode reaction or that can be adsorbed on the electrode." Electrolyte is stored externally, generally in tanks, and is typically pumped through the cell (or cells) of
