Engineers Create Material for High-Performance 'Supercapacitor'

Taking a significant step toward improving the power delivery of systems ranging from urban electrical grids to regenerative braking in hybrid vehicles, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have synthesized a material that shows high capability for both the rapid storage and release of energy.
A synthesized form of niobium oxide could be used in a "supercapacitor," a device that combines the high storage capacity of lithium ion batteries and the rapid energy-delivery ability of common capacitors.

UCLA researchers said the development could lead to extremely rapid charging of devices, ranging in applications from mobile electronics to industrial equipment. Supercapacitors, for example, are currently used in energy-capture systems that help power loading cranes at ports, reducing the use of hydrocarbon fuels such as diesel.
