However, their electrochemical\nperformances are largely hampered by the low flexibility and durability of current polyvinyl alcohol\n(PVA) based electrolytes. Herein, a novel polyvinyl alcohol-polyethyleneimine (PVA-PEI) based,\nconductive and elastic hydrogel was devised as an all-in-one electrolyte platform for wearable\nsupercapacitor (WSC). For proof-of-concept, we assembled all-solid-state supercapacitors based on\nboron nitride nanosheets (BNNS) intercalated graphene electrodes and PVA-PEI based gel electrolyte.\nFurthermore, by varying the electrolyte ions, we observed synergistic effects between the hydrogel\nand the electrode materials when KOH was used as electrolyte ions, as the Graphene/BNNS@PVAPEI-\nKOH WSCs exhibited a significantly improved areal capacitance of 0.35 F/cm2 and a smaller\nESR of 6.02 ohm/cm2. Moreover, due to the high flexibility and durability of the PVA-PEI hydrogel\nelectrolyte, the developed WSCs behave excellent flexibility and cycling stability under different\nbending states and after 5000 cycles. Therefore, the conductive, yet elastic, PVA-PEI hydrogel\nrepresents an attractive electrolyte platform for WSC, and the Graphene/BNNS@PVA-PEI-KOH\nWSCs shows broad potentials in powering wearable electronic devices.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/ma14081955","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.mdpi.com/1996-1944/14/8/1955","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1996-1944","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Wang, Chan"}],"nameIdentifiers":[{"nameIdentifier":"1027046","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuan, Hu"}],"nameIdentifiers":[{"nameIdentifier":"1027047","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Liu, Ying"}],"nameIdentifiers":[{"nameIdentifier":"1027048","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Ming-Rong"}],"nameIdentifiers":[{"nameIdentifier":"1027049","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Zhiwei"}],"nameIdentifiers":[{"nameIdentifier":"1027050","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Li, Zhou"}],"nameIdentifiers":[{"nameIdentifier":"1027051","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuan, Hu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1027052","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Ming-Rong","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1027053","nameIdentifierScheme":"WEKO"}]}]},"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":"Flexible Supercapacitors Based on Graphene/Boron Nitride Nanosheets Electrodes and PVA/PEI Gel Electrolytes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Flexible Supercapacitors Based on Graphene/Boron Nitride Nanosheets Electrodes and PVA/PEI Gel Electrolytes"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-14"},"publish_date":"2021-04-14","publish_status":"0","recid":"82769","relation_version_is_last":true,"title":["Flexible Supercapacitors Based on Graphene/Boron Nitride Nanosheets Electrodes and PVA/PEI Gel Electrolytes"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:56:50.824697+00:00"}
