Assistant professor Ya Ji's group recently published a paper named “Directional Regulation on Single-Molecule Redox-Targeting Reaction in Neutral Zinc-Iron Flow Batteries” in Joule.

Abstract:

With the widespread deployment of renewable energy, redox flow batteries have emerged as a vital technology for large-scale energy storage. Among them, redox-targeting flow batteries surpass the energy density limitations of traditional flow batteries, which are constrained by the solubility of the electrolyte, significantly enhancing energy density. However, the current approach to developing targeted flow batteries often relies on the random screening of solid materials and redox mediators to match potentials, posing significant obstacles to their practical application.

This work elucidates the relationship between the potential difference of redox mediators and solid materials within the targeting system, demonstrating its impact on capacity improvement. By directionally regulating the potential of the solid material, we have constructed a high-energy density redox-targeting system. This regulation strategy holds promise for other flow battery cells, enabling the prediction of the feasibility of redox-targeting systems between solid materials and redox mediators with varying potentials.
