Renewable energy sources have been a topic of ever-increasing interest, not least due to escalating environmental changes. The significant rise of research into energy harvesting and storage over the years has yielded a plethora of approaches and methodologies, and associated reviews of individual aspects thereof. Here, we aim at highlighting a rather new avenue within the field of batteries, the (noaqueous) all-organic redox-flow battery, albeit seeking to provide a comprehensive and wide-ranging overview of the subject matter that covers all associated aspects. This way, subject matter on a historical perspective, general types of redox-flow cells, electrolyte design and function, flow kinetics, and cell design are housed within one work, providing perspective on the all-organic redox-flow battery in a broader sense.

“…As an engineering plastic, polyimide (PI) has excellent mechanical property, thermal stability, radiation resistance, and chemical stability and is widely used as an aerogel material. , Because of its unique molecular structure, PI is difficult to dissolve in many organic solvents to fabricate aerogel. The feasible way is to introduce hydrophilic units through structural design to dissolve PI or to prepare PI aerogels by imidization starting from polyamic acid (PAA). , The former method is expensive and difficult to produce on a large scale.…”

In this study, polyimide (PI)/carbon fiber (CF) aerogel was fabricated via a freeze-drying method. The introduction of CF endows PI aerogels with good dimensional stability in the thermal imidization process. The resulting aerogel possesses excellent mechanical property (as high as 58.45 MPa) and good hydrophobic property (contact angle above 120°). The PI/CF aerogel also has very good radiation resistance, with a compressive modulus of 50.45 MPa even after 10 MGy irradiation, which is 86.53% of the initial modulus. These characteristics make the PI/CF aerogel very suitable for applications in radiation environment. Subsequently, a carbon aerogel with high temperature resistance and good mechanical properties was obtained by carbonization of the PI/CF aerogel. Its comprehensive property is comparable to traditional porous carbon-bonded carbon fiber composites.

“…Furthermore, the CE and EE of a VRFB with this membrane were 3.8% and 5.2% higher than those of the Nafion 212 membrane, respectively. Then, Xu et al 88 prepared a novel porous cross-linked polyimide membrane (PCrPI), which had ultrahigh chemical stability and could effectively block vanadium ion migration, reduce surface resistance, and had good durability. Moreover, the efficiency of the PCrPI membrane is significantly higher than Nafion 212.…”

Vanadium redox flow batteries (VRFBs) can effectively solve the intermittent renewable energy issues and gradually become the most attractive candidate for large-scale stationary energy storage. However, their low energy density and high cost still bring challenges to the widespread use of VRFBs. For this reason, performance improvement and cost reduction of VRFBs are the keys to their commercialization and large-scale energy storage applications. On the basis of this, this perspective briefly describes the development status of renewable energy and energy storage technology and summarizes the existing bottlenecks that affect the development of VRFBs. Meanwhile, the critical technologies of VRFBs are reviewed, and the research progress in recent years and the challenges that need to be overcome are introduced. This perspective focuses on four aspects, including core component material, system modeling, optimization operations, and future business challenges. Then, a comprehensive analysis of critical issues and solutions for VRFB development are discussed, which can effectively guide battery performance optimization and innovation. The views in this perspective are expected to provide effective and extensive understanding of the current research and future development of vanadium redox flow batteries.
