摘要：
The effect of Al addition on the hydrogen storage performance of LiBH4 was investigated. It is indicated that the onset dehydrogenation temperature of LiBH4/Al mixture is decreased to about 300 degrees C. The main hydrogen release shifts to low temperature with the increase of Al content. Furthermore, the dehydrogenated LiBH4/Al sample can be rehydrogenated at 600 degrees C and 10 MPa, significantly lower than that of the plan LiBH4. The improvement of hydrogen storage properties in LiBH4/Al system is due to the formation of LiAl and AlB2 compounds during the dehydrogenation.
