By capturing the emitted hard X-ray emitted during the core-hole decay, we can probe the electronic structure and local environment of the system. Measuring specific emissions originating from the quenching of core-holes from the valence orbital is known as Valence-to-Core emissions, which is rich in information about the nature of the hybridization and the chemical state. In this study, lab-scale XES\/XAFS is used to study the structural and electronic changes occurring in layered transition metal oxide batteries. Together, these techniques can help track the total spin-state, oxidation state as well as local interatomic changes. Several additional insights are gained by using XES and XAFS together to find the band gap of the system, and its changes over the course of delithiation.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EExamining Layered Lithium-Ion Batteries Using X-ray Absorption\/Emission Spectroscopy\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Examining Layered Lithium-Ion Batteries Using X-ray Absorption\/Emission Spectroscopy"}],"uid":"27707","created_gmt":"2025-07-02 17:10:44","changed_gmt":"2025-07-02 17:11:32","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-07-08T09:00:00-04:00","event_time_end":"2025-07-08T11:00:00-04:00","event_time_end_last":"2025-07-08T11:00:00-04:00","gmt_time_start":"2025-07-08 13:00:00","gmt_time_end":"2025-07-08 15:00:00","gmt_time_end_last":"2025-07-08 15:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Love 295  and via Teams","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
