The effect of complex halides and binary halides on hydrogen release for the 2LiBH4:1MgH2 system
Abstract
Due to the high hydrogen capacity of LiBH4, various strategies have been investigated to improve the hydrogen release properties of LiBH4. Theoretical calculations suggest that doping LiBH4 with F−/Cl− anions may generate lattice substitutions (such as the formation of LiBH3F or LiBH2F2), which will lower the hydrogen release temperature from LiBH4. The effect of addition of F−/Cl− containing dopants (viz. LiBF4, NH4F, LiAlCl4 and NH4Cl) on the hydrogen release from 2LiBH4:1MgH2 was investigated and LiBF4 was found to be the most effective among the dopants studied. Furthermore, the combined effect of LiBF4 and the
