Abstract:

70640 Advanced electrochemical devices with high power density and fast charge rate capability (less than 10 minutes) are needed for hybrid electric vehicles. Existing electrode materials and battery configurations are not capable of providing the necessary performance at low cost. This project will develop a new class of nanostructured tungsten oxide anodes with high electrical conductivity, and implement it in an asymmetric hybrid energy storage device. This device, with a lithium-intercalating anode such as tungsten oxide, a carbon cathode, and a non-aqueous electrolyte, will have high rate capabilities with a discharge time as small as 3 minutes, and a charge time as small as 6 minutes for a long cycle life (> 1000). In Phase I, a novel synthesis process will be used to produce nanostructured tungsten oxide powders that are intimately mixed with ultrafine carbon particles, achieving high electronic conductivity in the anodes. The nanocomposite powders will be tested in a hybrid cell configuration for their electrochemical properties. Commercial Applications and Other Benefits as described by the awardee: Asymmetric hybrid energy storage devices utilizing nanostructured tungsten oxide anodes should satisfy the emerging needs of propulsion systems for hybrid electric vehicles (HEVs) where both fast discharge and charge rates are desired. These batteries are also suited for other commercial applications, such as power tools and uninterrupted power supplies.
