<div>Aqueous organic redox flow batteries have many appealing properties in the application of large-scale energy storage. The large chemical tunability of organic electrolytes shows great potential to improve the performance of flow batteries. Computational studies at the quantum-mechanics level are very useful to guide experiments, but in previous studies explicit water interactions and thermodynamic effects were ignored. Here, we applied the computational electrochemistry method based on ab initio molecular dynamics to calculate redox potentials of quinones and their derivatives. The calculated results are in excellent agreement with experimental data. We mixed side chains to tune their reduction potentials, and found that solvation interactions and entropy effects play a significant role in side-chain engineering. Based on our calculations, we proposed several high-performance negative and positive electrolytes. Our first-principles study paves the way towards the development of large-scale and sustainable electrical energy storage.</div>

Excellent Stability

We report a ferric-air, solid oxide battery that consists of a tubular solid oxide cell with Ca(OH)2/CaO dispersed Fe/FeOx powders integrated as the redox-active materials in the fuel chamber. The key feature here is the use of Ca(OH)2 to prevent agglomeration and coarsening of Fe/FeOx powders, and more importantly to enable in situ production of H2/H2O as the electrochemical active redox couple in the fuel electrode. The proof-of-concept solid oxide battery exhibits an energy capacity of 144 Wh kg-1-Fe at a ferric utilization of 18.8% and excellent stability in ten discharge/charge cycles with a voltage efficiency of 83% that have great potential for improvement. These results showed encouraging promise of the ferric-air, solid oxide batteries for electrical energy storage applications.
