Influence of compositing conditions for Si-composite negative electrodes in sulfide-type all-solid-state lithium-ion batteries

Autor: Hiroshi Nagata, Junji Akimoto, Kunimitsu Kataoka

Publikováno v: New Journal of Chemistry. 47:8479-8483

The battery performances of Si-composite electrodes are strongly influenced by the compositing process strength caused by the reaction between Si and the solid electrolyte for all-solid-state batteries.

Ion-exchange synthesis and improved Li insertion property of lithiated H2Ti12O25 as a negative electrode material for lithium-ion batteries

Autor: Kunimitsu Kataoka, Hideaki Nagai, Tomoyuki Sotokawa, Yoshimasa Kumashiro, Yoichi Ishibai, Junji Akimoto

Publikováno v: Journal of Asian Ceramic Societies, Vol 4, Iss 1, Pp 75-80 (2016)

We successfully prepared the lithiated H2Ti12O25 sample by the H+/Li+ ion exchange synthetic technique in the molten LiNO3 at 270 °C using H2Ti12O25 as a starting compound. Chemical composition of the obtained lithiated H2Ti12O25 sample was determin

Single-crystal synthesis and structure refinement of La2Li0.5Al0.5O4 with K2NiF4-type structure

Autor: Naoki Hamao, Kunimitsu Kataoka, Junji Akimoto

Publikováno v: Journal of Asian Ceramic Societies, Vol 3, Iss 3, Pp 301-304 (2015)

Single crystals of lanthanum lithium aluminum oxide, La2Li0.5Al0.5O4, were synthesized for the first time by a flux method at 773 K. The La2Li0.5Al0.5O4 single crystal is colorless, has an average size of 60 μm with a square platelet shape, and crys

Structural Change and Morphological Surface Degradation upon Electrochemical Li Extraction from a Single Crystal of Spinel-type LiNi0.5Mn1.5O4

Autor: Yuki Hamada, Kunimitsu Kataoka, Yoshitaka Matsushita, Yasushi Idemoto, Junji Akimoto, Naoya Ishida

Publikováno v: Crystal Growth & Design. 20:4533-4539

The space-group change and surface degradation of spinel-type LiNi0.5Mn1.5O4 upon the Li extraction reaction at 4.9 V were investigated using single-crystal samples. The stoichiometric LiNi0.5Mn1.5...
