Journal ArticleDOI
Ionic Conduction in Lithium Ion Battery Composite Electrode Governs Cross-sectional Reaction Distribution
Yuki Orikasa,Yuma Gogyo,Hisao Yamashige,Misaki Katayama,Kezheng Chen,Takuya Mori,Kentaro Yamamoto,Titus Masese,Yasuhiro Inada,Toshiaki Ohta,Zyun Siroma,Shiro Kato,Hajime Kinoshita,Hajime Arai,Zempachi Ogumi,Yoshiharu Uchimoto +15 more
TL;DR: The 6-probe method can measure electronic/ionic conductivity in composite electrodes with changing electrode porosities and shows that the ionic conductivity is decreased for lower porosity electrodes, which governs the reaction distribution of composite electrodes and their performances.
Journal ArticleDOI

Atul D. Sontakke,Atul D. Sontakke,Jumpei Ueda,Jian Xu,Kazuki Asami,Misaki Katayama,Yasuhiro Inada,Setsuhisa Tanabe +7 more
TL;DR: In this paper, a systematic study on Ce3+ luminescence in amorphous borate glass and make a comparison with the well-known polycrystalline Y3Al5O12:Ce3+ (YAG-Ce) phosphor was presented.
Journal ArticleDOI
X-ray absorption fine structure imaging of inhomogeneous electrode reaction in LiFePO 4 lithium-ion battery cathode
Misaki Katayama,Koichi Sumiwaka,Ryota Miyahara,Hisao Yamashige,Hajime Arai,Yoshiharu Uchimoto,Toshiaki Ohta,Yasuhiro Inada,Zempachi Ogumi +8 more
TL;DR: In this paper, the spatial distribution of electrode redox reaction for LiFePO 4 cathode was analyzed by X-ray absorption fine structure (XAFS) imaging, which revealed the inhomogeneity of the chemical state of Fe during the charge/discharge process.
Journal ArticleDOI
Combined adsorption and oxidation mechanisms of hydrogen sulfide on granulated coal ash
Satoshi Asaoka,Shinjiro Hayakawa,Kyunghoi Kim,Kazuhiko Takeda,Misaki Katayama,Tamiji Yamamoto +5 more
TL;DR: X-ray absorption fine structure analyses showed hydrogen sulfide was adsorbed onto the granulated coal ash and successively oxidized by manganese oxide (III) contained in the material.
Journal ArticleDOI
Mechanisms of Hydrogen Sulfide Removal with Steel Making Slag
Kyunghoi Kim,Satoshi Asaoka,Tamiji Yamamoto,Shinjiro Hayakawa,Kazuhiko Takeda,Misaki Katayama,Takasumi Onoue +6 more
TL;DR: It is demonstrated here that the SMS is a promising material to remediate organically enriched coastal sediments in terms of removal of hydrogen sulfide.
