The two cells have the same configuration consisting of a nanoporous gold (NPG) air electrode and a ceramic separator of fast sodium ion conductor, NASICON. Only the selection of catholyte, either alkyl carbonate-based nonaqueous solution of NaClO4 or aqueous solution of NaOH, is different. All performances are demonstrated to be better for the aqueous one. Lower overpotential of aqueous cell leads to better round-trip efficiency. A large resistance relevant to oxygen reduction reaction in the nonaqueous cell is relieved by changing the catholyte to the aqueous electrolyte, affording higher rate capability and power density. The aqueous electrolyte is also effective to remove the limitation of the discharge capacity defined by the volumetric amount of air electrode, as has been claimed in previous studies on aqueous Na-air cells. Furthermore, the aqueous cell is demonstrated to be robust and less sensitive and to atmosphere. The NPG electrode works reversibly in the half-cell reaction of the aqueous cell, while an electrodeposition of metallic Na on the anode during charging requires an improvement."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699995329699456","@type":"Researcher","foaf:name":[{"@value":"Taijyu Hashimoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995329699457","@type":"Researcher","foaf:name":[{"@value":"Katsuro Hayashi"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00134686"}],"prism:publicationName":[{"@value":"Electrochimica Acta"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2015-11","prism:volume":"182","prism:startingPage":"809","prism:endingPage":"814"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0013468615305648?httpAccept=text/plain"},{"@id":"https://api.elsevier.com/content/article/PII:S0013468615305648?httpAccept=text/xml"}],"createdAt":"2015-10-07","modifiedAt":"2018-09-18","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004232122834176","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Dual–phase Spinel MnCo 2 O 4 Nanocrystals with Nitrogen-doped Reduced Graphene Oxide as Potential Catalyst for Hybrid Na–Air Batteries"}]},{"@id":"https://cir.nii.ac.jp/crid/1360017280631072512","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Enhanced Electrochemical and Transportation Properties in a NASICON-Type Na<sub>3</sub>Zr<sub>2</sub>(SiO<sub>4</sub>)<sub>2</sub>(PO<sub>4</sub>)–Na<sub>3</sub>Ti<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> Junction Prepared by Spin Coating and Glass-Ceramic Processes"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707099729536","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A dense NASICON sheet prepared by tape-casting and low temperature sintering"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707335944576","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Liquid exfoliation graphene sheets as catalysts for hybrid sodium-air cells"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567182076133504","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Hybrid Sodium–Air Cell with Na[FSA–C2C1im][FSA] Ionic Liquid Electrolyte"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567183099773952","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Novel High-Energy-Density Rechargeable Hybrid Sodium–Air Cell with Acidic Electrolyte"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282763131713408","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Revisiting Oxide-Based Sodium Ion Conductors for Next-Generation Batteries"},{"@language":"ja","@value":"次世代電池にむけて再注目される酸化物系ナトリウムイオン伝導体"},{"@language":"ja-Kana","@value":"ジセダイ デンチ ニ ムケテ サイチュウモク サレル サンカブツケイ ナトリウムイオン デンドウタイ"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.electacta.2015.09.153"},{"@type":"OPENAIRE","@value":"doi_dedup___::20fb1ba01d090cf8a453d287ff120099"},{"@type":"CROSSREF","@value":"10.1016/j.electacta.2017.05.100_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"},{"@type":"CROSSREF","@value":"10.1021/acsaem.2c03022_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"},{"@type":"CROSSREF","@value":"10.2320/materia.58.440_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"},{"@type":"CROSSREF","@value":"10.1016/j.electacta.2016.09.113_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"},{"@type":"CROSSREF","@value":"10.1021/acsami.8b04278_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"},{"@type":"CROSSREF","@value":"10.1016/j.matlet.2016.10.054_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"},{"@type":"CROSSREF","@value":"10.1016/j.electacta.2018.05.020_references_DOI_CRf8T79ISyyeXcWqV5DKqTj1774"}]}
