Abstract: In this paper, the microstructure and hydrogen storage properties of the (NaH/Al)+x(molar fraction, %) Ti(x=0, 4, 6, 10) composites were investigated. It was found that the reversible hydrogen storage properties can be improved by mechanically ball-milling the(NaH/Al) mixture together with Ti powder.
