Abstract Redox flow batteries (RFBs) are a promising option for long‐duration energy storage (LDES) due to their stability, scalability, and potential reversibility. However, solid‐state non‐aqueous have low safety conductivity, while aqueous systems using vanadium zinc expensive power densities, limiting industrial application. An approach lower capital cost improve scalability is utilize cheap Earth‐abundant metals such as iron (Fe). Nevertheless, all‐iron RFBs many complications, involving voltage loss from ohmic resistance, side reactions hydrogen evolution, oxidation, most significantly electrode plating, dendrite growth. To address these issues, researchers begun examine the effects of various alterations RFBs, adding organic ligands form Fe complexes slurry instead common materials graphite or platinum rods. Overall, progress in improving at its infant stage, new strategies must be introduced, utilization nanoparticles, which can limit growth increasing capacity. This review provides an in‐depth overview current research offers perspectives on how design next generation RFBs.

Abstract Fluorenones are suitable candidates for negolytes in flow batteries, as they demonstrate the ability to store 2 electrons, and can achieve reversibility, solubility, stability with appropriate molecular design. However, limitations persist such use of alkaline media, high redox potentials, a limited scope optimization. Herein, azoniafluorenones is reported novel class negolytes. They be readily accessed highly modular fashion from inexpensive commercially available materials (e.g., boronic acids). Variations substitution patterns reveal 3‐substituted N ‐alkylated AZON3, which demonstrates excellent solubility at neutral pH (1.64 m ) two low reversible potentials (−0.31 −0.58 V vs Ag/AgCl). AZON3 exhibits when evaluated concentration supporting electrolyte (1 3 KCl), paired BTMAP‐Fc on positive side. Capacity retentions 99.95% 99.91% per cycle (99.35% 99.21% day) achieved cycling 1 respectively, coupled volumetric capacity 46.4 Ah L −1 (87% utilization).
