Development and Characterization of Novel Cation-Disordered Battery Electrode Materials

The emergence of cation-disordered battery electrode materials represents a major progress in solid-state materials for electrochemical energy storage applications. The disordered distribution of cations allows rich opportunities in designing diverse cation-disordered structures/compositions but also bring challenges in understanding their nature and energy storage mechanism. In this presentation, we will demonstrate our effort in developing all-new cation-disordered battery electrode materials and investigating their electrochemical properties. Moreover, we will present our approach in characterizing the unique structural features and working mechanisms of these novel electrode materials via a comprehensive array of spectroscopic techniques, ranging from X-ray absorption, solid-state UV-Vis absorption, vibrational spectroscopy, etc. Results of the work will bring transformative insights for various subfields of energy storage materials and investigation of hidden yet critical materials properties via in-depth spectroscopic characterizations.
