Circulating Flow Batteries offer a scalable and efficient solution for energy storage, essential for integrating renewable energy into the grid. This study evaluates various electrolyte compositions, membrane materials, and flow configurations to optimize performance. Key metrics such as energy density, cycle life, and efficiency are analyzed. Experimental results show high energy efficiency and long cycle life, making Circulating Flow Batteries suitable for large-scale applications. The modular design allows easy scaling, and their rapid response capability supports grid stability with intermittent renewable sources. Future research should focus on enhancing materials and reducing costs to fully realize the potential of Circulating Flow Batteries in sustainable energy systems.
