We create high-performance, sustainable energy storage solutions through electrode chemistry and electrolyte design innovations.
Explore Our Story
Laboratory of Energy Transformation & Sustainability (LETS) aims to provide transformative solutions for powering a sustainable future.
Our research focuses on fundamental electrochemical conversion reactions and kinetics, electrolyte solvation structure and their interactions with electrodes, abuse under extreme conditions, advanced characterizations combining simulations.
By integrating innovations in both electrode chemistry and electrolyte design, we can develop sustainable electrochemical energy storage devices with higher power and energy.
Main Research Directions
Our research focuses on three pivotal areas of battery technology, each aimed at revolutionizing energy solutions on a global scale.
Electrolyte Design & Interphases
Revolutionizing electrolyte technologies from aqueous to solid-state for better battery performance.
Anionic redox-based cathodes
Developing high-capacity, metal-free cathodes to maximize lithium-ion battery energy density.
Advanced Characterizations
Uncovering SEI/CEI formation mechanisms to optimize electrolytes and enhance battery cycle life.
