Abstract

The formation condition of an intermediate compound of LiBH₄ during the partial dehydriding reaction and its local atomistic structure have been experimentally investigated. LiBH₄ changes into an intermediate compound accompanying the release of approximately 11 mass % of hydrogen at 700-730 K. The Raman spectra indicate that the B-H bending and stretching modes of the compound appear at lower and higher frequencies, respectively, as compared to those of LiBH₄. These features are consistent with the theoretical calculation on the monoclinic Li₂B₁₂H₁₂, consisting of Li⁺ and [B₁₂H₁₂]^2- ions, as a possible intermediate compound of LiBH₄.
