Among various cathode materials, MnO\u2082 stands out because of its abundance, non-toxicity, and structural versatility.\u003C\/p\u003E\u003Cp\u003EThis study investigates the synthesis, structural characterization, and electrochemical performance of electrodeposited MnO\u2082 polymorphs as cathode materials for AZIBs. Phase-controlled MnO\u2082 films were successfully fabricated via electrodeposition by tuning precursor chemistry and deposition conditions. Cathodic deposition from KMnO\u2084-based electrolytes produced layered \u03b4-MnO\u2082, while acidic MnSO\u2084-based systems enabled the formation of \u03b5-MnO\u2082. Structural analysis using X-ray diffraction confirmed the phase evolution and highlighted the strong influence of substrate and deposition parameters on crystallinity and film quality. Electrochemical testing revealed that electrodeposited MnO\u2082, consisting of 100% active material without binders, exhibited higher specific capacity compared to commercial \u03b2-MnO\u2082.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EOverall, this work demonstrates that electrodeposition is an effective route for phase-controlled synthesis of MnO\u2082 and provides insights into structure\u2013performance relationships for improving AZIB cathodes.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EElectrodeposition-derived MnO2 \u0026nbsp;as a Cathode Material for Aqueous Zinc-ion Batteries\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Electrodeposition-derived MnO2  as a Cathode Material for Aqueous Zinc-ion Batteries"}],"uid":"27707","created_gmt":"2026-04-07 20:35:43","changed_gmt":"2026-04-07 20:35:43","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-14T14:00:00-04:00","event_time_end":"2026-04-14T15:00:00-04:00","event_time_end_last":"2026-04-14T15:00:00-04:00","gmt_time_start":"2026-04-14 18:00:00","gmt_time_end":"2026-04-14 19:00:00","gmt_time_end_last":"2026-04-14 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"MRDC 3515 Conference Room or virtually 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":""}}}
