NSF Grant to study Oxide Anodes for High-Performance Aqueous Batteries

We received an NSF grant from CBET Electrochemical System program. Collaborative Research: Fundamental Study of Niobium Tungsten Oxide Anodes for High-Performance Aqueous Batteries

Modern human society requires efficient, affordable and safe means for energy storage. Today, rechargeable lithium–ion batteries dominate the energy storage landscape from portable electronics to the rapidly expanding electric vehicles and electricity (grid) storage applications. However, current lithium-ion batteries suffer from safety and cost issues, primarily because of flammable, moisture-sensitive and expensive organic solvents used in the electrolytes. This project is aimed at replacing the organic solvent electrolyte with water, in a manner that does not compromise on battery performance (i.e., volumetric and gravimetric energy and power density). To accomplish this, the research team proposes to explore new classes of complex oxide (niobium tungsten oxide) materials that will be designed specifically for aqueous battery chemistries, enabling breakthrough improvements in volumetric energy and power density for the next generation of aqueous batteries. This work will contribute to low-cost, high-performance and safe aqueous batteries that are critical for large-scale energy storage. Click Here for more details.
