Juyeon joined the National Physical Laboratory in 2018 and leads the energy storage theme of the Electrochemistry Group. She is expert in physical and electrochemical interpretation techniques for battery performance analysis.
Juyeon received her PhD in Physical Chemistry from Seoul National University, South Korea, where her research focused on characterising electronic structure, morphology and charge transfer dynamics of organic/(semi)metal interfaces. After working at the Free University of Berlin (Germany) and collaborating with RIKEN and Osaka University (Japan), she moved to Samsung SDI (Korea), which is one of the largest suppliers for lithium-ion battery production.
At Samsung, Juyeon led the electrochemical part in establishing DB for battery modelling and developed holistic approach of cell degradation mechanism based on post mortem analysis correlated to electrochemical tests. As a principal engineer she led projects for Jaguar Land Rover and BMW, considering cell validation, safety and the quality control of mass production.
Areas of interest
Juyeon is working on a range of battery projects to create innovative standard test methods and to unveil fundamental mechanisms of battery performance and degradation. Her current research interests involve the development of in situ / operando measurements of energy storage systems, validation of battery modelling with reliable test protocols, and fundamental understanding for the impacts of inhomogeneity on multi-domain and multi-scale system operation.
