Enhanced hydrogen storage performance of LiBH4-Ni composite
Journal of Alloys and Compounds 479(2009)545-548，-0001，（）：
The hydrogen storage properties of LiBH4 ball milled with various ratios of Ni powders were investigated. It was found that Ni addition improved the dehydrogenation of LiBH4, resulting in the majority of hydrogen released from LiBH4 below 600℃. According to van't Hoff equation, the desorption enthalpy of LiBH4-Ni system was calculated to be H=-60.76 kJ mol-1 H2, which is similar to that of the pure LiBH4. Pressure-composition-temperature (PCT) results revealed that Ni addition accelerate the dehydrogenation rate of LiBH4. Furthermore, the LiBH4-Ni system could be reversed partly at 600℃ and 10MPa hydrogen pressure.
