In recent years, redox flow batteries (RFBs) and derivatives have attracted wide attention from academia to the industrial world because of their ability to accelerate large-grid energy storage. Although vanadium-based RFBs are commercially available, they possess a low energy and power density, which might limit their use on an industrial scale. Therefore, there is scope to improve the performance of RFBs, and this is still an open field for research and development. Herein, a combination between a conventional Li-ion battery and a redox flow battery results in a significant improvement in terms of energy and power density alongside better safety and lower cost. Currently, Li-ion redox flow batteries are becoming a well-established subdomain in the field of flow batteries. Accordingly, the design of novel redox mediators with controllable physical chemical characteristics is crucial for the application of this technology to industrial applications. This Review summarizes the recent works devoted to the development of novel redox mediators in Li-ion redox flow batteries.
近年来，氧化还原液流电池（RFBs）及其衍生物因其在加速大电网储能方面的能力而受到学术界和工业界的广泛关注。尽管基于钒的氧化还原液流电池已商业化，但它们的能量和功率密度较低，这可能会限制其在工业规模上的应用。因此，有改进氧化还原液流电池性能的空间，这仍然是一个开放的研发领域。在此，传统锂离子电池与氧化还原液流电池的结合在能量和功率密度方面带来了显著提高，同时安全性更好、成本更低。目前，锂离子氧化还原液流电池正在成为液流电池领域一个成熟的子领域。因此，设计具有可控物理化学特性的新型氧化还原介质对于该技术在工业应用中的应用至关重要。本综述总结了近期致力于锂离子氧化还原液流电池中新型氧化还原介质开发的工作。
