Aqueous Flow Batteries for Energy Storage

Special Issue banner


The renewable energies like solar and wind are becoming a central topic of our time due to the critical issues of energy and environment. However, these renewable energy sources are intermittent and often unpredictable, which induce a low-quality output electricity and further affect their stability in grid. Electricity energy storage (EES) technology, which could store and release electricity as needed, therefore, becomes an effective way to solve these problems. Flow batteries as one kind of EES technologies have received considerable attention in large scale energy storage due to their attractive features like flexible design, good safety, high energy efficiency and environmental benignity. The recent development of flow battery especially the vanadium flow battery (VFB), has been increasingly rapid. Demonstrations with scale from 10s kW to MW have been successfully carried out, which confirms the availability and possibility of flow battery for large-scale energy storage. At the same time, many new flow battery systems with high energy density and low cost have been emerging to maintain the sustainable development of flow batteries. This issue will focus on the current status of flow battery development, including the new flow battery systems from inorganic to organic based batteries, as well as the key factors that affect the final commercialization of flow batteries.
