Strategically Modified Ligand Incorporating Mixed Phosphonate and Carboxylate Groups to Enhance Performance in All‐Iron Redox Flow Batteries (Adv. Energy Mater. 1/2025)

Redox Flow Batteries A novel iron-ligand complex offers a cost-effective approach for aqueous redox flow batteries by using abundant iron. Reengineering ligands having both phosphonate and carboxylate groups enhances battery output voltage, accelerates electron transfer, and enables ligand reorientation, advancing understanding of redox chemistry in coordination complexes and supporting renewable energy integration.
