摘要 水溶性有机液流电池自2014年出现后发展迅猛,特别是近些年来有机电活性物质的降解和二聚导致的容量衰减问题得到初步解决后,该类液流电池有望作为大规模储能系统的候选者。然而能量密度较低的问题限制了其商业化的进程。对此,主要从增大溶解度、提高电化学窗口和电子的得失数这3个方面详细介绍了5种提高水溶性有机液流电池能量密度的方法——分子结构剪裁、“interaction-mediating”策略的应用、采用聚合物电活性物质、“氧化还原靶向”原理和电极表面的改性,同时对进一步提高水溶性有机液流电池能量密度的策略进行了简要展望。

Abstract: The aqueous organic flow battery has been developed rapidly since its appearance in 2014, especially in recent years, after the degradation and dimerization of organic electroactive substances have been initially solved, and this type of redox flow battery is expected to be a candidate for large-scale energy storage systems. However, the problem of low energy density limits its commercialization process. This article mainly introduces in detail the five method of increasing the energy density of aqueous organic redox flow batteries, such as tailoring the molecular structure, the application of "interaction-mediating" strategy, the use of polymer electroactive materials, the application of redox-targeting reactions and modification of the electrode surface from three aspects: increasing solubility, expanding electrochemical window and increasing the number of electron transfers. At the same time, the strategy to further increase the energy density of aqueous organic redox flow batteries is briefly prospected.
