The development of charge-storage materials for use in redox flow batteries (RFBs) requires possession of a diverse property set that will lead to high capacities, voltages, and lifetimes for large-scale stationary storage application. High capacities require high solubilities in all states of charge. High voltages stem from large differences in redox potentials. Long lifetimes require...
Li-ion batteries that can charge rapidly without sacrificing lifetime are crucial for the further development of electric vehicles (EVs) and for better customer acceptance. Measuring transport properties such as ionic conductivity and viscosity are simple and effective techniques for screening electrolyte suitability for fast charge applications. The use of low-viscosity esters as co-solvents...
Redox flow batteries, which utilize solutions of active materials (anolyte and catholyte) rather than the solid state electrodes found in conventional batteries, are highly promising for stationary energy storage applications. Whereas most redox flow cells are based on metallic active species in aqueous media, we have been working on developing flow batteries based on solutions of redox active...
Redox flow batteries are a promising solution for large-scale energy storage. Many flow batteries have been successfully commercialized; however, these systems typically involve the use of expensive metallic redox couples such as vanadium, iron-vanadium and iron-chromium, which exceed the US Department of Energy’s cost target of $100 kWh-1.
One approach to reducing systems costs involves...
