Abstract
A series of graphite- and Ni-coated hydrogen storage alloys were prepared with simple ball-mill method, and their hydrogen storage behaviors were characterized and compared with bare alloys. The results showed that the oxygen resistance of the graphite-coated materials increased, while the hydrogen storage kinetics decreased significantly. For the Ni-coated materials, oxygen resistance was noticeably improved and excellent oxygen resistance was achieved with sufficient Ni loading, while the hydrogen storage capacity and kinetics were also maintained or even improved. Our results show that the elemental coating method is an effective method to improve the oxygen resistance of hydrogen storage alloys, which brings about new insights into the design of these materials.
