摘要：

Low-temperature performance and high-rate discharge capability of AB(5)-type non-stoichiometric hydrogen storage are studied. X-ray diffraction(XRD), pressure-composition-temperature(PCT) curves and electrochemical impedance spectroscopy(EIS) are applied to characterize the electrochemical properties of AB(x) (x=0.8, 4.9, 5.0, 5.1, 5.2) alloys. The results show that the non-stoichiometric alloys exhibit better electrochemical properties compared with that of the AB(5) alloy.
