Multiscale modelling of lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries hold the promise of becoming the next generation battery technology for automotive and transport applications due to its 2-3 times higher energy density than today’s lithium-ion batteries. Li-S technology is being actively developed by major industry players like Sony and LG Chem as well as technology start-ups such as UK’s Oxis Energy.

About

This PhD project aims to advance the understanding of the degradation mechanisms in Li-S batteries which is a major obstacle for the technology’s mass-market adoption.

Mathematical models will be developed to capture the fundamental electrochemical processes contributing to the degradation of Li-S batteries at different length scales, from interfaces to the bulk of the electrodes. Once validated against electrochemical measurements, these degradation models will be integrated into an existing Li-S modelling framework we have recently developed in collaboration with Imperial College London and Oxis Energy.

The ageing-aware battery model will be further utilised to optimize Li-S battery pack control for automotive applications. There will be collaboration opportunities with Imperial College London and Oxis Energy for battery testing and simulations.

Eligibility criteria

Applicants should have:

  • A relevant degree (first or upper second) in engineering, physics or chemistry.
  • Experience in or mathematical modelling, computer programming (C++, Matlab, Python) and/or FEA analysis.

IELTS Academic: 6.5 or above (or equivalent) is required, with no sub-test score less than 6.

How to apply

Applicants are required to send a cover letter explaining your interest in and qualifications for the project, a CV, and the names and contact details of two references.

Formal applications can be made through our Automotive Engineering PhD programme page.

Applications will be reviewed when received, and shortlisted candidates will be interviewed.
