“…To increase the cell voltage, it is pivotal that the redox potential of the posolyte to have a higher positive value (regardless of whether it is positive or negative), while the redox potential of the negolyte should have a lower negative value (regardless of whether it is positive or negative). [29,30] The cell voltage can be increased by choosing appropriate redox couples with proper functionalization. The solubility of a substance is regulated by the chemical and physical properties of both solute and solvent.…”

In recent years, there has been considerable interest in the potential of quinones as a promising category of electroactive species for use in aqueous organic redox flow batteries. These materials offer tunable properties and the ability to function as both positive and negative electrolytes, making them highly versatile and suitable for a range of applications. Ongoing research has focused on improving the stability, solubility, and performance of quinones, with a particular emphasis on the creation of stable negolytes. The pairing of these advancements with alternate chemistries has created new prospects for commercial applications. However, challenges persist regarding the stability of quinones in high‐potential electrolytes and the limited number of viable quinones available. Despite these obstacles, significant strides have been made, and the potential for quinones to revolutionize energy storage technology is vast. This review article provides a comprehensive overview of recent progress in this area, with a specific focus on redox potential, solubility, and stability, and offers valuable insights into the future of quinone‐based aqueous organic redox flow batteries.

State‐of‐the‐art applications of computational fluid dynamics (CFD) in the analysis and optimization of electrochemical reactors and redox flow batteries are reviewed. Various factors are covered which affect the efficiency of electrochemical reactors and redox flow batteries created using CFD simulation approaches, including physical and chemical factors, such as pH, treatment time, temperature, and the conductivity of the solution, as well as design elements like inter‐electrode distance and electrode materials. Different hydrodynamic variables are discussed that impact the efficiency of these systems, such as pressure distribution, velocity, tracer mass fraction, geometry, flow‐based electrochemical energy storage, and residence time distribution. Although CFD methods are reliable, more straightforward, and cost‐effective, also the limitations of CFD and the challenges are considered that remain in its development and application in electrochemical engineering. The significant progress made in the use of CFD to study electrochemical reactors and redox flow batteries and the technology's potential to improve the efficiency and sustainability of these technologies are emphasized.
