摘要：
与锂离子电池相比，氧化还原液流电池（RFB）在长时间、大规模的储能应用中广受关注。本综述深入探讨了能源存储中最重要的挑战之一：如何降低RFB的成本。解决这一问题最直接有效的手段，是开发低成本材料和高溶解性氧化还原化学反应体系。高水溶性无机氧化还原对对于开发高能量密度和低成本储能技术具有重要意义。此外，合理设计有机氧化还原分子并优化其在液态和非液态体系中的性质也有很大的潜力。许多新的概念已经开始模糊传统电池和RFB之间的界限，在识别/开发膜和分离器，以及控制电极表面副反应等方面，也需要突破。

Compared to lithium-ion batteries, redox-flow batteries have attracted widespread attention for long-duration, large-scale energy-storage applications. This review focuses on current and future directions to address one of the most significant challenges in energy storage: reducing the cost of redox-flow battery systems. A high priority is developing aqueous systems with low-cost materials and high-solubility redox chemistries. Highly water-soluble inorganic redox couples are important for developing technologies that can provide high energy densities and low-cost storage. There is also great potential to rationally design organic redox molecules and fine-tune their properties for both aqueous and non-aqueous systems. While many new concepts begin to blur the boundary between traditional batteries and redox-flow batteries, breakthroughs in identifying/developing membranes and separators and in controlling side reactions on electrode surfaces also are needed.
