Such flexibility, however, typically comes at a price of reduced mechanical stability, which leads to component deterioration and, eventually, failure. Here, we identify an optimised building block for silicon-based lithium-ion battery (LIB) anodes, fabricate it with a ligand- and effluent-free cluster beam deposition method, and investigate its robustness by atomistic computer simulations. A columnar amorphous-silicon film was grown on a tantalum-nanoparticle scaffold due to its shadowing effect. PeakForce quantitative nanomechanical mapping revealed a critical change in mechanical behaviour when columns touched forming a vaulted structure. The resulting maximisation of measured elastic modulus (~120 GPa) is ascribed to arch action, a well-known civil engineering concept. The vaulted nanostructure displays a sealed surface resistant to deformation that results in reduced electrode-electrolyte interface and increased Coulombic efficiency. More importantly, its vertical repetition in a double-layered aqueduct-like structure improves both the capacity retention and Coulombic efficiency of the LIB.", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_publisher": "Nature Portfolio"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1038/s43246-021-00119-0", "subitem_relation_type_select": "DOI"}}]}, "item_10001_relation_17": {"attribute_name": "Related site", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://www.nature.com/articles/s43246-021-00119-0", "subitem_relation_type_select": "URI"}}]}, "item_10001_rights_15": {"attribute_name": "Rights", "attribute_value_mlt": [{"subitem_rights": "© 2021 The Author(s)."}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2662-4443", "subitem_source_identifier_type": "ISSN"}]}, "item_10001_version_type_20": {"attribute_name": "Author\u0027s flag", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2021-05-12"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Haro-2021-Nano-vault architecture mitigates st.pdf", "filesize": [{"value": "2.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)", "licensetype": "license_free", "mimetype": "application/pdf", "size": 2100000.0, "url": {"label": "Haro-2021-Nano-vault architecture mitigates st", "url": "https://oist.repo.nii.ac.jp/record/2047/files/Haro-2021-Nano-vault architecture mitigates st.pdf"}, "version_id": "914a446a-73bf-42fe-93b4-de208206527d"}]}, "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": "Nano-vault architecture mitigates stress in silicon-based anodes for lithium-ion batteries", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Nano-vault architecture mitigates stress in silicon-based anodes for lithium-ion batteries", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "30", "path": ["58"], "permalink_uri": "https://oist.repo.nii.ac.jp/records/2047", "pubdate": {"attribute_name": "公開日", "attribute_value": "2021-05-12"}, "publish_date": "2021-05-12", "publish_status": "0", "recid": "2047", "relation": {}, "relation_version_is_last": true, "title": ["Nano-vault architecture mitigates stress in silicon-based anodes for lithium-ion batteries"], "weko_shared_id": 30}
