Postdoctoral Researcher, 2019 – Present
Stewart studied for his MChem Chemistry with a Year in Industry at the University in Bath, graduating in 2015 with first-class honours. His industrial year as an analytical chemist included a Gas Chromatography project to simultaneously analyse organic vapours and atmospheric gases. Under the supervision of Professor Mark Weller, he gained an interest in energy materials investigating polyanionic materials as solid-state electrolytes for rechargeable-ion batteries, gaining invaluable experience in single crystal and powder XRD techniques.
Stewart’s PhD under Professor John Irvine, entitled ‘Multivalent Thermal Batteries: Concept, Development and Advances” included studies on the physical and electrochemical properties of magnesium and calcium, along with tailoring full cells to produce novel multivalent battery chemistries.
He has now taken up a position as a Postdoctoral Researcher within the group, firstly working on high-temperature sodium battery chemistries, and now as a PDRA on The Faraday Institution NEXGENNA sodium-ion battery project looking into materials properties during scaling up from coin to pouch cells.
