A flow battery is a rechargeable in which an containing one or more dissolved electroactive elements flows through an that reversibly converts to . Electroactive elements are "elements in solution that can take part in an electrode reaction or that can be on the electrode." Electrolyte is stored externally, generally in tanks, and is typically pumped through the cell (or c.

This paper discusses the current state of energy storage, elucidates the technical advantages and challenges faced by zinc-iron flow batteries, and provides an in-depth analysis of their application advantages in the field of energy storage, along with future prospects. . Recently, aqueous zinc–iron redox flow batteries have received great interest due to their eco-friendliness, cost-effectiveness, non-toxicity, and abundance. Zinc-iron flow batteries. . Zinc-based flow battery technologies are regarded as a promising solution for distributed energy storage. Nevertheless, their upscaling for practical applications is still confronted with challenges, e., dendritic zinc and limited areal capacity in anodes, relatively low power density, and. .
