Multiscale models for solid-state battery materials
Supervisor: Lukasz Figiel (WMG)
Extreme volumetric expansion, high temperature gradients, and/or high-frequency vibrations, can cause microscale damage phenomena in solid-state batteries, and thus compromise their structural integrity and safety. The objective of this project is to develop multi-scale (micro-to-macro) models that will enable design and analysis of new polymer composite electrolytes with fast-ion conducting particles for future solid-state batteries. Microscale considerations will capture material microstructure and in-situ processes within the electrolyte and surrounding electrodes. Numerical solutions to those microscale problems will generate surrogate microscale models that will be connected with the macroscale via a data-driven homogenisation approach with uncertainty quantification..
