Black Phosphorus as a High-Capacity, High-Capability Negative Electrode for Sodium-Ion Batteries: Investigation of the Electrode/Electrolyte Interface
Mouad Dahbi,Mouad Dahbi,Naoaki Yabuuchi,Naoaki Yabuuchi,Mika Fukunishi,Kei Kubota,Kei Kubota,Kuniko Chihara,Kazuyasu Tokiwa,Xue Fang Yu,Xue Fang Yu,Hiroshi Ushiyama,Hiroshi Ushiyama,Koichi Yamashita,Koichi Yamashita,Jin Young Son,Yi-Tao Cui,Hiroshi Oji,Shinichi Komaba,Shinichi Komaba +19 more
TL;DR: In this article, surface characterization techniques are combined for investigation on the electrode/electrolyte interface of the black phosphorus electrodes with polyacrylate binder to understand the formation of a solid electrolyte interphase (SEI) in alkyl carbonate ester and its evolution during cycling.
Journal ArticleDOI
Phosphorus Electrodes in Sodium Cells: Small Volume Expansion by Sodiation and the Surface-Stabilization Mechanism in Aprotic Solvent
Naoaki Yabuuchi,Naoaki Yabuuchi,Yuta Matsuura,Toru Ishikawa,Satoru Kuze,Jin Young Son,Yi-Tao Cui,Hiroshi Oji,Shinichi Komaba,Shinichi Komaba +9 more
TL;DR: In this article, the electrode performance of amorphous phosphorus in aprotic Na cells is examined, and it is found that severe electrolyte decomposition results in insufficient reversibility of the electrode materials, owing to the highly reactive Na3P surface.
Journal ArticleDOI
Sodium carboxymethyl cellulose as a potential binder for hard-carbon negative electrodes in sodium-ion batteries
Mouad Dahbi,Mouad Dahbi,Nakano Takeshi,Naoaki Yabuuchi,Naoaki Yabuuchi,Toru Ishikawa,Kei Kubota,Kei Kubota,Mika Fukunishi,Sota Shibahara,Jin Young Son,Yi-Tao Cui,Hiroshi Oji,Shinichi Komaba,Shinichi Komaba +14 more
TL;DR: In this paper, a hard carbon negative electrode with CMC binder demonstrates the superior reversibility and cycleability in NaPF6 propylene carbonate solution at room temperature to that with ordinary poly(vinylidene difluoride) (PVdF) binder.
Journal ArticleDOI
