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. 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.
