Final Technical Report: SISGR: The Influence of Electrolyte Structure and Electrode Morphology on the Performance of Ionic-Liquid Based Supercapacitors: A Combined Experimental and Simulation Study
- University of Utah
Obtaining fundamental understanding and developing predictive modeling capabilities of electrochemical interfaces can significantly shorten the development cycles of electrical double layer capacitors (EDLCs). A notable improvement in EDLC performance has been achieved due to recent advances in understanding charge storage mechanisms, development of advanced nanostructured electrodes and electrochemically stable electrolytes. The development of new generation of EDLCs is intimately linked to that of nanostructured carbon materials which have large surface area, good adsorption/desorption properties, good electrical conductivity and are relatively inexpensive. To address these scientific challenges the efforts of an interdisciplinary team of modelers and experimentalists were combined to enhance our understanding of molecular level mechanisms controlling the performance of EDLCs comprised of room temperature ionic liquid (RTIL) electrolytes and nanostructured carbon-based electrodes and to utilize these knowledge in the design of a new generation of materials and devices for this energy storage application. Specifically our team efforts included: atomistic molecular dynamics simulations, materials science and electrode/device assembly, and synthesis and characterization of RTIL electrolytes.
