| Abstract Scope |
The emergence of cation-disordered Li-ion battery electrode materials represents a major progress in materials chemistry research in energy storage applications. One major strength of cation-disordered oxide cathodes is that these materials can be primarily or even fully based on Mn, an earth abundant transition metal, offering a decisive advantage in sustainability. In this presentation, we demonstrate our work in exploring the chemical and structural space of Na-Mn-based cation-disorder cathodes and understanding their structural-performance relationship. 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 into various subfields of Na-ion battery materials research and investigation of properties of cation-disordered materials via in-depth spectroscopic characterizations. |
