All-iron flow batteries are a technology development that offer a potential long-lasting solution to safely, efficiently and cost-effectively storing renewable energy. Within the past decade this technology and its potential impact on grid-level energy storage has been extensively researched.
All-soluble all-iron redox flow batteries (AIRFBs) are an innovative energy storage technology that offer significant financial benefits. Stable and affordable redox-active materials are essential for the commercialization of AIRFBs, yet the battery stability must be significantly improved to achieve practical value.
Herein, we propose a highly stable alkaline all-iron flow battery for LDES by pairing the [Fe (CN) 6] 3− / [Fe (CN) 6] 4− redox couple with the ferric/ferrous-gluconate (Gluc −) complexes redox couple, which exhibits high solubility (1.2 mol L −1), fast redox kinetics and high stability in alkaline media.
All-iron flow batteries are a safer alternative to other metals frequently used in electrochemical energy storage devices, such as lithium. While lithium hydrates are toxic, flammable, react violently with water and corrode in air, iron is a relatively non-toxic alternative that is only slightly reactive with water and air.
Companies like ESS Tech, Inc. in the USA have made significant strides in developing and commercializing acidic all-iron ARFBs and the U.S. Advanced Research Projects Agency-Energy estimates that this iron-based flow battery would achieve an energy storage cost as low as $125 per kWh .
In summary, an alkaline all-iron flow battery was constructed by coupling ferric/ferrous-gluconate complexes with the [Fe (CN) 6] 3− / [Fe (CN) 6] 4−.
