Professor Grey is best known for her work in nuclear magnetic resonance (NMR) to study electrochemical energy storage, with the goal of improving lithium and sodium ion battery capacity in function in electric vehicle applications as well as for storage and load-leveling on the electrical grid. She is in considerable demand worldwide for her research into new strategies to improve battery lifespans, with current research supported by the Faraday Institution. A recent article about Prof. Grey said her research “can impact the lives of the world’s poorest three billion people”.
