Summary
I’m currently a PhD student at Imperial College London in the Department of Civil and Environmental Engineering under the supervision of Dr Emilio Martinez-Paneda. I am currently working on the topic of All-Solid-State Battery FEM modelling. We are trying to quantify the most challenging problem that is hindering the commercial application of this promising next-generation battery and provide design inspirations to the battery engineers through the model. The main platform I use is COMSOL Multiphysics.
Project details
The first commercial lithium-ion (Li-ion) batteries were introduced in 1991 by Sony Co. and have greatly changed the lifestyle of modern people. Most of the Li-ion batteries in the market are liquid-state Li-ion batteries (LSLB). They are low in energy density, have safety concerns and are toxic to the environment. In recent years, various alternatives to LSLB have been proposed. All-solid-state Li-ion battery (ASSLB) is a promising one. ASSLBs have a higher energy density, safer and more environmentally friendly. However, the initiation and growth of Li dendrites and the void formation at the electrode/electrolyte interface are hindering the massive application of ASSLBs. Our project aims at developing a multi-couple phase-field model that incorporates electro-chemo-mechanical effect and could capture the interface morphology changes to predict the initiation and evolution of the dendrites, voids etc. Investigating the critical conditions to suppress dendrites' growth and provide insight for future ASSLB designs.
