Dynamic metal-anode flow battery energy-storage system

A dynamic metal-anode flow battery energy-storage system, comprising:

• a discharge module including at least one metal-air battery which includes a plurality of discharge reactants in a first electrolyte, wherein the discharge reactants react with oxygen in air to form a plurality of discharged products and discharge electric energy;
• a charging module, being electrically connected to the discharge module and including at least one electrolysis device and at least one removal device, wherein the at least one electrolysis device includes a conductive member and a plurality of electrolysis reactants immersed in a second electrolyte;
• the electrolysis reactants are electrolyzed to form a plurality of electrolysis products which are adhered to a surface of the conductive member;
• the electrolysis products and the discharge reactants are of the same material;
• the at least one removal device includes a scraper adapted to remove the adhered electrolysis products from the surface of the conductive member;
• and
• a delivery device adapted to deliver the electrolysis products into the first electrolyte as the discharge reactants, and deliver the discharged products into the second electrolyte as the electrolysis reactants.
