Title: "High Performance Two – Dimensional Transition Metal Dichalcogenide based Flexible Supercapacitors"
Mentor: Yeonwoong Jung, Ph.D, Materials Science and Engineering, University of Central Florida
Institution: University of Central Florida
Abstract:
With huge research interest in the development of flexible/bendable electronic devices, it is imperative to develop flexible energy storage systems powering up these electronics. Supercapacitors are considered the viable solution for the emerging flexible technology as they surpass state-of-art Li-ion batteries in cycle life, safety, fast charging, and wide temperature operation range. The weak point in supercapacitors is their low energy density andit willrequire serious research efforts to mitigate the limitation of limited energy density. Here, wedevelop a rational design of one-body core/shell nanowire array as binder-free electrodes for high-performance flexible supercapacitors. One dimensional (1D) hexagonal tungsten trioxide (h-WO3) nanowires were seamlessly integrated with conformal 2D transition metal dichalcogenide (TMD) tungsten disulfide (WS2) layers in one-body geometry by sequential oxidation/sulfurization of the tungsten foil. These hybrid heteromaterials outperform previously developed any stand-alone 2D TMD-based supercapacitor electrodes; particularly, exhibiting remarkable cyclic stability, remaining at 100% of the initial capacitance even after 30,000 charge−discharge cycles. The novel supercapacitor electrode design presented here shows great potential for a variety of energy storage devices compatible with emerging flexible and wearable technologies with unprecedented functionalities.
