Asymmetric Hybrid Supercapacitor Based on V2O5/CNT Nanocomposite

Tech ID: 24581 / UC Case 2010-298-0

Innovation

Yunfeng Lu and colleagues have devised a high-performance energy storage device based on vanadium oxide (V2O5) /carbon nanotube (CNT) nanocomposites that provides an asymmetric supercapacitor with a high energy and power density. Current supercapacitor designs are comprised of organic electrolyte or titanium oxide-based nanowires coupled with CNTs as electrodes. This technology utilizes cost-effective V2O5/CNT nanocomposites of a hierarchical fibrous structure as cathodes for asymmetric supercapacitors, leading to increased capacitance and conductivity of electrodes for high-performance devices. The technology has wide applications in heavy-duty facilities, electric vehicles, mobile electrical tools, and consumer electronics.
