Although cation-disordered rocksalt phases with a stoichiometric composition (Li : Mn molar ratio = 1 : 1) are expected to be electrochemically less active, both samples show superior performance as electrode materials when compared with thermodynamically stable layered phases in Li/Na cells. Both metastable samples deliver large reversible capacities, which correspond to >80% of their theoretical capacities, with relatively small polarization on the basis of reversible Mn3+/Mn4+ redox. Moreover, for rocksalt LiMnO2, the phase transition into a spinel phase is effectively suppressed compared with a thermodynamically stable phase. The electrode reversibility of NaMnO2 is also drastically improved by the use of the metastable phase with good capacity retention. Metastable phases with unique nanostructures open a new path for the design of advanced electrode materials with high energy density, and thus a broad impact is anticipated for rechargeable Li/Na battery applications.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry "}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1039/C8TA03667E","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12603290","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"20507488","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Applied Chemistry, Tokyo Denki University"},{"subitem_text_value":"Department of Applied Chemistry, Tokyo Denki University"},{"subitem_text_value":"Department of Applied Chemistry, Tokyo Denki University / Elements Strategy Initiative for Catalysts and Batteries, Kyoto University"},{"subitem_text_value":"Technology Department, Electronic Materials Group, JX Nippon Mining & Metals Corporation"},{"subitem_text_value":"Department of Applied Chemistry, Tokyo Denki University / Elements Strategy Initiative for Catalysts and Batteries, Kyoto University / Department of Chemistry and Life Science, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sato, Takahito"}],"nameIdentifiers":[{"nameIdentifier":"35835","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Kei"}],"nameIdentifiers":[{"nameIdentifier":"35836","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhao, Wenwen"}],"nameIdentifiers":[{"nameIdentifier":"35837","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kajiya, Yoshio"}],"nameIdentifiers":[{"nameIdentifier":"35838","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yabuuchi, Naoaki"}],"nameIdentifiers":[{"nameIdentifier":"35834","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80529488","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80529488"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-01"}],"displaytype":"detail","filename":"2018 JMCA LiMnO2 NaMnO2.pdf","filesize":[{"value":"5.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2018 JMCA LiMnO2 NaMnO2.pdf","url":"https://ynu.repo.nii.ac.jp/record/9966/files/2018 JMCA LiMnO2 NaMnO2.pdf"},"version_id":"2876c97c-e008-4b0e-94dd-7bdd00e53dd2"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Metastable and nanosize cation-disordered rocksalt-type oxides: revisit of stoichiometric LiMnO2 and NaMnO2","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Metastable and nanosize cation-disordered rocksalt-type oxides: revisit of stoichiometric LiMnO2 and NaMnO2"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-06-13"},"publish_date":"2019-06-13","publish_status":"0","recid":"9966","relation_version_is_last":true,"title":["Metastable and nanosize cation-disordered rocksalt-type oxides: revisit of stoichiometric LiMnO2 and NaMnO2"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:00:38.874223+00:00"}
