The Grey Group

The Grey group studies the nature of solid state materials by nuclear magnetic resonance (NMR), X-ray and Neutron scattering, electron microscopy and computational calculations. The materials we investigate have applications in supercapacitors, fuel cells, and batteries. 

Our current research projects are described here and a full list of publications is available here. We currently have 49 group members including 3 Master students, 22 PhD students (11 students being co-supervised) and 21 Post-Doctoral researchers all listed here. The group is very dynamic and also very international with almost 20 nationalities represented.

Recent News:

Welcome to our new Post-Doc Dr. Darren Ould. Darren will be working on the NEXGENNA sodium ion batteries project specifically focussing on developing new electrolytes for these systems.

Welcome to Vera Kunz who joined the group as a PhD student in April.

Team Redox Flow has recently had their research featured in an article about the uses of MRI and NMR in helping to design systems for large-scale storage of renewable energy, it can be found here.

Congratulations to Dr. Evan Wenbo Zhao who has been awarded the STFC Futures Early Career Award to work on a collaborative project on redox flow batteries with Prof. Michael Aziz at the Harvard University.

One of our group members, Evelyna Wang, has recently published an article on the effects of atmospheric gases on Li metal cyclability and solid-electrolyte interphase formation. She also gave a presentation that can be viewed online here.

One of our group members, Dr David Hall, was recently featured on the Naked Scientists podcast, where he discussed how electric car batteries work.

Welcome to Dominic Hey who joined the group as a PhD student in January.
