Research Scientist working the Division of Material Physics, Department of Physics, Chalmers University of Technology.
Hi, I’m Matthew, a Researcher living in Gothenburg, Sweden. My research focuses on using operando methodologies to investigate mechanisms (chemical and physical) that underpin the way in which batteries store energy.
I recently defended my thesis titled 'Operando Investigations of Materials and Processes of Next Generation Batteries' at a public defence held at Chalmers University of Technology in January 2022. A copy of the thesis can be read by follow the links below.
I am orgininally from the UK, where I grew up in Bournemouth, on the south coast, and subsequently attended the University of Southampton to achieve my Master of Chemistry degree.
I have an acute interest in using X-ray Tomographic Microscopy to investigate the structures formed when using Li-metal, a technology that has the potential to enable high-energy density batteries.
Here, we report the development of an operando synchrotron X-ray tomographic microscopy method capable of probing in real-time the formation, growth, and dissolution of Li microstructures during the cycling of a Li||Cu cell containing a standard non-aqueous liquid electrolyte solution.
In this work we explored the use of a full field-of-view operando Tomography methodology to monitor the changes in mass if elemental sulfur, and the subsequent precipitation of lithium sulfide during the discharge of a lithium sulfur battery.
In this work we used operando Raman Spectroscopy to monitor changes to polysulfide concentration across multiple charge/discharge cycles of a Lithium-Sulfur battery, to explore the relationship between chemical species observed in the electrolyte and cell performance.
