The effect of NH3 content on hydrogen release from LiBH4-NH3 system

As compared to Co-Li(NH3)4/3BH4 (17.8 wt% H2), the Co-Li(NH3)2BH4 dehydrogenates at lower temperatures with faster rate but at the expense of the H2 capacity (14.3 wt%). In the case of Co-Li(NH3)BH4, fairly pure H2 (99.99%) with comparative amount of H2 (15.3 wt%) can be obtained.
