Multi-Scale Modelling and Design of All-Solid-State Batteries (Ref: AAE-ZN-2516)

All-solid-state batteries (ASSBs) are considered one of the most promising next-generation energy storage technologies due to their enhanced safety, high energy density, and long cycle life. However, the performance of ASSBs critically depends on the design and optimisation of the electrode microstructure, where ion and electron transport, mechanical stresses, and electrochemical reactions are strongly coupled.

This PhD project will focus on the multi-scale modelling and design of solid-state battery electrodes using COMSOL Multiphysics. By combining electrochemical, mechanical, and thermal simulations with structural design and optimisation, the project aims to establish design principles for high-performance electrodes in solid-state lithium batteries. The PhD candidate will investigate the structure–performance relationships in solid-state electrodes through:

1. Multi-physics simulation with COMSOL: coupled electrochemical–thermal–mechanical modelling of ASSB electrodes and modelling solid–solid interfaces, ion transport limitations, and stress generation.
2. Electrode structure design and optimisation: parametric studies of porosity, particle size distribution, and layer thickness, and optimisation of composite electrode design to balance ionic and electronic conductivity with mechanical stability.

We encourage and will provide support to candidates in pursuing government funding to sponsor their studies, such as scholarships offered by the China Scholarship Council (CSC). Please note that strict deadlines apply for such funding opportunities.
