The aqueous iron (Fe) redox flow battery here captures energy in the form of electrons (e-) from renewable energy sources and stores it by changing the …
Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.
Therefore, it is necessary to develop high energy density and low-cost flow batteries to meet the requirements of large-scale energy storage and make full use of renewable energy [[35], [36], [37]]. Zinc as an energy storage active substance has the advantages of high redox activity, abundant reserve, and non-toxic properties, so zinc …
