Shin Ichi Orimo,Yuko Nakamori,G. Kitahara,Kazutoshi Miwa,Nobuko Ohba,Towata Shinichi,Andreas Züttel +6 more
TL;DR: In this paper, structural differences in LiBH 4 before and after the melting reaction at approximately 550 K were investigated to clarify the experimental method for the confirmation of reversible dehydriding and rehydriding reactions.
Journal ArticleDOI
First-principles study on lithium borohydride Li B H 4
TL;DR: In this article, an orthorhombic phase observed at ambient conditions and predicted its fundamental properties; the structural properties, electronic properties, dielectric properties, vibrational properties, and the heat of formation.
Journal ArticleDOI
Experimental studies on intermediate compound of LiBH4
Shin Ichi Orimo,Yuko Nakamori,Nobuko Ohba,Kazutoshi Miwa,Masakazu Aoki,Shin Ichi Towata,Andreas Züttel,Andreas Züttel +7 more
TL;DR: In this article, the formation condition of an intermediate compound of LiBH4 during the partial dehydriding reaction and its local atomistic structure have been experimentally investigated, and the Raman spectra indicate that the bending and stretching modes of the compound appear at lower and higher frequencies, respectively, as compared to those of Li BH4.
Journal ArticleDOI
Dehydriding and rehydriding processes of well-crystallized Mg(BH4)2 accompanying with formation of intermediate compounds
Hai Wen Li,Kentaro Kikuchi,Yuko Nakamori,Nobuko Ohba,Kazutoshi Miwa,Towata Shinichi,Shin Ichi Orimo +6 more
TL;DR: In this article, it was shown that approximately 6.1% of hydrogen can be reversibly stored for the sample of Mg(BH 4 ) 2 after the dehydriding reaction, through the formation of a possible intermediate compound such as MgB 12 H 12.
