To develop economically feasible fast-charging batteries, several improvements in overall cell architecture, electrochemically inactive components, and intrinsic properties of electrochemically active materials must be made. The current thesis seeks to optimize the rate capability and stability of anode and cathode material through atomic doping and to pair the material with a suitable electrolyte in a full cell. Two active materials are chosen for modification: the recently discovered high-rate anodic oxide TiNb\u003Csub\u003E2\u003C\/sub\u003EO\u003Csub\u003E7\u003C\/sub\u003E\u0026nbsp;(TNO) and the high-voltage cathodic oxide LiMn\u003Csub\u003E1.5\u003C\/sub\u003ENi\u003Csub\u003E0.5\u003C\/sub\u003EO\u003Csub\u003E4\u0026nbsp;\u003C\/sub\u003E(LMNO). Initial experimental results show that cationic metal dopants with a d\u003Csup\u003E0\u003C\/sup\u003E\u0026nbsp;electron configuration are most suitable for increasing the electronic and ionic transport properties of TNO. Additionally, similar d\u003Csup\u003E0\u003C\/sup\u003E atomic dopants were found to increase the stability of LMNO cathode materials. The thesis seeks to build on these initial discoveries by selecting suitable liquid and solid electrolytes to increase the temperature stability of active materials and to mitigate the evolution of gas during continued cycling. The work provides insight into the effect of atomic doping on active material, fundamental insight into gas evolution phenomena related to Ti\u003Csup\u003E4+\u003C\/sup\u003E containing active materials, and electrolyte strategies to enable the commercial implementation of inexpensive, high-rate, and temperature-stable lithium-ion battery full cells.\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u201cDevelopment of Electrode Materials for High-Rate Lithium-Ion Batteries"}],"uid":"27707","created_gmt":"2020-12-02 19:59:38","changed_gmt":"2020-12-02 19:59:38","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-12-11T11:00:00-05:00","event_time_end":"2020-12-11T13:00:00-05:00","event_time_end_last":"2020-12-11T13:00:00-05:00","gmt_time_start":"2020-12-11 16:00:00","gmt_time_end":"2020-12-11 18:00:00","gmt_time_end_last":"2020-12-11 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
