Institute for Nonferrous Metals, Beijing 100088, China Received 15 July 2007; accepted 10 September 2007 Abstract: The as-prepared Ti-Zr hydride powder is used as dopant to improve hydrogen storage...% (mass fraction) after 10 hydrogenation/dehydrogenation cycles. These results show the Ti-Zr hydride doped NaAlH4 has good reversible hydrogen storage capacity and kinetics. XRD and SEM investigations......
dischargeability, and the improved cycling stability is due to their lower volume expansion on hydriding and more uniform composition. Key words: hydrogen storage alloy; Co-free alloy; material processing... hydrogen concentration in the alloy bulk, mol/cm3; Cs the hydrogen concentration on the electrode surface, mol/cm3; d the density of the hydrogen storage alloy, g/cm3; t the discharge time, s; and F......
