Lee Johnson is a Director for the Lithium Air Batteries program at EIT and a Professor of Electrochemistry with expertise in electrochemical energy devices at The University of Nottingham. He jointly leads the Nottingham Applied Materials and Interfaces Group with colleagues Darren Walsh and Graham Newton.

Since 2012, his research interests have focused on the development of next-generation energy storage including lithium-air batteries, magnesium batteries, lithium-sulfur batteries and electrolyte solutions for nickel-rich and high-voltage lithium-ion cells. His research is supported by funding from EPSRC, the Supergen Energy-Storage Hub, and the Faraday Institution, where he is a co-investigator on the LiSTAR and FutureCat projects.

He received a MChem (Hons.) degree from Newcastle University in 2006 after which he completed a PhD in physical chemistry and electrochemistry at the University of Nottingham. In 2011 he was awarded a EPSRC Doctoral Prize.

In 2012 he joined the research group of Prof Sir P.G. Bruce FRS (University of St Andrews 2012-2014, University of Oxford 2014-2017). In 2017 he was awarded a Nottingham Research Fellowship, closely followed by an EPSRC Fellowship. In 2019 he was promoted to Associate Professor and then to Professor in 2025.
