<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>

Practical interest in redox flow batteries has arisen in recent decades as a result of intensive development in the field of alternative energy (such as solar and wind) and the control of peak loads in industrial electrical networks. It turned out that large-scale energy storage systems used to compensate fluctuations in the process of solar and wind generation of energy in the production of electric vehicles and power supply systems for large households, are more profitable when working on redox flow batteries. Firstly, they are easy to scale, and secondly, the energy stored in such batteries is cheaper. In recent years, the interest of researchers in the redox behavior of simple and substituted quinones and anthraquinones used as potential components of electrochemical energy storage systems has grown significantly. The main advantages of organic redox systems are scalability, kinetic advantages over the used redox systems based on inorganic substances, reconstructability (a wide possibility of changing electrochemical and chemical properties by introducing various functional groups into organic molecules) and environmental safety. Therefore, in this work, the electrochemical behavior of some promising organic systems based on quinone, anthraquinone and their analogs to be used as redox systems of flow batteries was studied using the method of cyclic voltammetry.
