Carbon Fibre Modification for Composites Structural Supercapacitors for Energy Storage Devices

Project overview

Driven by the need for the development of new materials that simultaneously perform structural and non-structural functions, the interest in multifunctional composite materials is rapidly increased. This research project is based on multifunctional development of new composite materials, which allows for full integration of the energy storage systems into the structural low weight components. The concept to be developed is multifunctional structural composite supercapacitors, which could significantly reduce the weight and volume in traditional energy storage devices and simultaneously serve as the load-carrying structural body. The work will provide a crucial contribution towards future zero emission vehicles, which requires energy efficiency, sustainability and environmental friendliness. In addition, such useful and innovative materials are strong candidates for a wide range of energy-depended applications, such as access panel for aircrafts, laptops, mobiles etc. The structural supercapacitor is consisted of modified polymeric electrolyte and two conductive carbon fabric electrodes, which are separated by a piece of electrically insulating glass fabric or polymer membrane. A crucial requirement for efficient structural composite supercapacitors is the development of electrode materials that possess high energy storage (i.e. high surface area) and stable electrochemical performance whilst under mechanical load. My research focuses on the development of high surface area carbon fabric electrodes using different activation approaches, such as chemical activation, carbon nanotube (CNT) sizing, and direct growth of CNTs on fibres.
