💡 Novelty & Significance:
The novelty is using iodide to form SnI62− intermediates that make the Sn4+/Sn2+ couple reversible, enabling a four-electron Sn4+/Sn0 anode. This yields a high-energy-density tin-based aqueous flow battery with 205 Wh l−1 anolyte energy density, 89% energy efficiency, and a kilowatt-scale stack stable over 1,000 hours.
