CFN Research Activities

My research aims describing specific mechanisms of electrochemical reactions and degradation of electrode materials using ex-situ and in-situ transmission electron microscopy. Particular interest includes real-time observation, and structural and chemical characterizations. Fundamental understandings on energy storage materials at the nano scale will provide valuable insights on designing novel materials with excellent performance.
