Recently, it has been reported that destabilizing LiBH4 by, i.e., MgH2, transition metal oxides and chlorides presents a promising approach to exert its potential for hydrogen storage. In the present study, we find that simple mechanical milling with Al in a mole ratio of 2:1, markedly improves the reversible dehydrogenation performance of LiBH4. The system possesses a theoretical capacity of 8.5wt. % and could be reversibly operated at 400-450°C. The combined property and phase examinations suggest that the observed property improvement should be associated with the formation of AlB2 in the dehydriding process. Further cyclic examination found that the system suffered from a serious capacity loss in the dehydriding/rehydriding cycles. A better understanding of the degradation mechanism may provide a means for further material property improvement.
