Redox flow batteries (RFBs) are promising energy storage candidates for grid deployment of intermittent renewable energy sources such as wind power and solar energy. Various new redox-active materials have been introduced to develop cost-effective and high-power-density next-generation RFBs. Electrochemical kinetics play critical roles in influencing RFB performance, notably the overpotential and cell power density. Thus, determining the kinetic parameters for the employed redox-active species is essential. In this Perspective, we provide the background, guidelines, and limitations for a proposed electrochemical protocol to define the kinetics of redox-active species in RFBs.
氧化还原液流电池（RFBs）是用于间歇性可再生能源（如风能和太阳能）电网部署的有前景的储能候选者。人们已引入各种新型氧化还原活性材料来开发具有成本效益且高功率密度的下一代RFBs。电化学动力学在影响RFB性能方面起着关键作用，尤其是过电位和电池功率密度。因此，确定所采用的氧化还原活性物质的动力学参数至关重要。在此观点文章中，我们为一种提议的电化学方案提供背景、指导方针和局限性，该方案用于定义RFBs中氧化还原活性物质的动力学。
