These recommendations can be broadly applied to a wide range of flow battery chemistries to facilitate future benchmarking and RFB development. The energy storage system (EES) is the bottleneck to the development of a smart/micro-grid and the widespread use of intermittent renewable power sources.
The flow battery is mainly composed of two parts: an energy system and a power system. In a flow battery, the energy is provided by the electrolyte in external vessels and is decoupled from the power.
The first iron-based flow battery was proposed in the 70s of the 20th century, with Fe (III)/Fe (II) and Cr (III)/Cr (II) serving as the positive and negative active components, respectively and HCl as the supporting electrolyte, which exhibited the battery voltage of 1.18 V.
Taking the widely used all vanadium redox flow battery (VRFB) as an example, the system with a 4-h discharge duration has an estimated capital cost of $447 kWh −1, in which the electrolyte and membrane account for 43% and 27% of the total cost, respectively [, , ].
Energy conversion is carried out in electrochemical cells similar to fuel cells. Most redox-flow batteries have an energy density comparable to that of lead-acid batteries, but a significantly longer lifespan. In the electrochemical cell, electrolyte solutions flow through the half-cell compartments of the plus and minus pole.
Based on the redox-targeting reaction of [Fe (CN) 6] 4-/3- and Prussian blue (PB), Wang Qing's team designed a redox-targeted flow battery with [Fe (CN) 6] 4-/3- as the redox mediator and PB as a solid energy storage material to break the solubility limitation of ferricyanide, which greatly improve the capacity of the system.

When replacing a sulfur with a nitrogen on the aromatic core, benzotriazole can show a much lower potential than benzotriazole due to the increase of π-electron density, resulting in another low-potential anolyte (−1.61 V vs SHE) for nonaqueous redox flow batteries. Similar methods can also be adopted to design high-potential catholytes with ...

The response speed of the flow battery system is slower than that of the lithium battery, so how to respond quickly when the power fluctuations occur in the power grid system is an important research topic. The following literature incorporates supercapacitors into energy storage systems to help speed up the response of the system. In 2024, Chen et al. 46] …
