PhD Studentship: Development of All-Inkjet-Printed Solid-State Flexible Supercapacitors (HUIO_U18SCI)

University of East Anglia - Mathematics (Engineering)

Start date: October 2018

Supervisor: Dr Oscar Hui

Project description: Applications are invited to the Engineering Division at the School of Mathematics, UEA, for a PhD in the field of nanotechnology, electrochemistry, and manufacturing for energy storage.

High performance electronics have accelerated the development of advanced energy storage device such as supercapacitors (SCs)) [1]. SCs have demonstrated higher power density, shorter charging time, longer cycle life, and better operational safety compared with some rechargeable batteries [2, 3]. However, practical applications of SCs are still seriously hindered due to the relatively poor performance of the electrode materials, such as low specific capacitance in carbon based materials, poor cycling stability in transition metal oxides, etc. [4, 5].

This PhD project aims to develop a novel inkjet-printed technology to print solid-state SCs on flexible substrates. The PhD candidate will prepare some nano-sized electrode materials with controllable physical, electrical, and chemical properties. The candidate will determine how the properties of the electrode materials influence the diffusion mechanism of gel electrolyte and the structural stability of the SCs. Finally, the candidate will evaluate the performance of the solid-state SCs in terms of specific capacity, rate performance, energy and power densities, and cycle life.

Interviews will be held w/c 22 January 2018.

Person specification: Acceptable first degree: Chemistry, Materials Science, Engineering, and other related disciplines will be considered.

The standard minimum entry requirement is 2:1.

Funding notes: This PhD project is in a Faculty of Science competition for funded studentships. These studentships are funded for 3 years and comprise home/EU fees, an annual stipend of £14,553, and £1000 per annum to support research training. Overseas applicants may apply but they are required to fund the difference between home/EU and overseas tuition fees (in 2017/18 the difference is £13,805 for the Schools of CHE, PHA, & MTH (Engineering) and £10,605 for CMP & MTH, but fees are subject to an annual increase).
