Computational Modelling for Energy Materials



About

We are a computational materials modelling group in the Materials and Metallurgy Department of the University of Birmingham. We use density-functional theory and other atomistic level modelling techniques to discover new materials for energy applications.
The creation of new materials is both difficult and expensive. It is very difficult to “see” the structure of these materials over the length scales that they work and very expensive to create prototype materials to test. Whilst experimental physics can use x-rays, high energy electrons or neutrons to infer the structure of these materials, this inference is made much more robust when combined with theoretical predictions of the kinds of structures that can be formed. In a computer we use quantum mechanical calculations to simulate the results of these kinds of experiments, helping to understand materials and suggest new materials with the kind of properties desired.










Dual behaviour of Alumina coatings on cathodes elucidated by theory and experiment

20 January 2025

In this combined theory and experimental work published in Energy and Environmental science we show the dual behaviour of alumina coatings in protecting high-capacity Ni rich NMC cathodes for Li-ion batteries. A plethora of experimental techniques like solid state NMR, XAS, OEMS combined with DFT+U calculations show the chemical effect...

Core-loss spectroscopy to demonstrate the efficacy of DFT functionals in modelling O K-edge XAS in Li-ion battery cathodes

12 November 2024

In this combined theory and experimental chem mater publication we show the efficacy of different DFT functionals based on their localisation in capturing the characteristics of O K edge XAS obtained experimentally for Li-ion battery cathodes. Our work focussing on the pre-edge and edge features show that hybridization, structural distortions,...
