Overview

Supercapacitor is a promising energy storage device with advantages of high power density, fast charging/discharging rate and long cycling life. However, the energy density of supercapacitor is relatively low as compared to that of other devices such as lithium-ion battery. To improve the energy density, new electrode materials including graphene and metal oxides have been explored for supercapacitor electrodes.

Two-dimensional (2D) heterostructures recently offered a compelling solution to enhance the performance of supercapacitors by combining more than one components into a single electrode. These 2D heterostructures are formed by stacking 2D materials with complementary properties of individual materials. By carefully arranging the layers of 2D materials, it is possible to obtain 2D heterostructures with tailored properties and improved electrochemical performance.

In this project, we are seeking one PhD applicants to explore vertical heterostructures made of 2D materials such as graphene, MXene and layered double hydroxides (LDHs). Domestic applicants are encouraged to apply. The student will receive an annual, tax-free PhD stipend (~$34,000 p.a.), along with eligibility for a fee-waiver scholarship from QUT for their degree.

Research activities

In the duration of the project the PhD student is expected to perform the following activities:

  • understand and fabricate 2D vertical heterostructures for supercapacitor electrodes
  • evaluate and optimize energy storage performance
  • mechanistic understanding and investigation via operando measurements and theoretical simulations.

Outcomes

The expected outcomes of this PhD project will include:

  • new methods of materials synthesis and electrode fabrication for supercapacitors
  • device assembly, system integration and performance evaluation
  • new knowledge generation for 2D heterostructures in energy storage devices
  • research publications in high-impact journals.

Skills and experience

To be considered for this PhD project, the candidate is expected to have the following skills and experience:

  • knowledge in electrochemistry and energy storage devices
  • experience in materials synthesis and characterization
  • publications in international journals in the related field.
