Research interestsSuper-capacitor based on mixed ionic liquid super-capacitors Super-capacitors are devices characterised by low energy densities (KWH KG-1) but high densities (KW KG-1). Therefore, they have a variety of potential applications such as regenerative breaking. They are the power source of choice in city buses being developed in China. Perhaps the main challenge is to increase the energy density of super-capacitors while keeping their power handling capabilities. This needs new material developments, such as new nanoporous materials used in electrodes. However, recent experiments have shown for the first time that using a mixture of ionic liquids can further enhance energy density, although the mechanisms for this are as yet unknown. This project will concentrate on understanding why mixed ionic liquids increase energy density using galvanostatic charge/discharge, electron microscopy, NMR and electrochemical impedence spectroscopy techniques. Optimisation of effect through parametric studies of different mixtures will also take place. This project is part of a large UK and European Consortium investigating energy storage technologies. |
