Flow Batteries- Synthesizing Molecules for High-Energy-Density Electrolytes and Highly-Selective Membranes in Grid Scale Energy Storage Systems

Abstract

Because of their huge capacity and outstanding cycling characteristics, flow batteries are considered viable options for grid-scale energy storage systems. However, the progress of efficient electrolytes and highly selective membranes is essential for the commercialization of flow batteries. In this paper, we synthesize molecules that can be used for flow batteries as strong electrolytes and extremely selective membranes. We find that the synthesis of these molecules is feasible using simple and commercially available materials. The results show that our proposed approach is effective in producing efficient electrolytes and highly selective membranes for flow batteries. This paper utilizes the flow battery as a platform to explore the potential of these molecules Ingrid-scale energy storage systems. The methodology of this study is promising and can be extended to other flow battery platforms. We achieved high energy densities and excellent cycling performances by using these molecules.
