Low-temperature performance and high-rate discharge capability of AB5-type non-stoichiometric hydrogen storage alloy

摘要：

Low-temperature performance and high-rate discharge capability of AB5-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 ABx (x=4.8,4.9,5.0,5.1,5.2) alloys.The results show that the non-stoichiometric alloys exhibit better electrochemical properties compared with that of the AB5 alloy.
