AB3-typed hydrogen storage alloy(Mm0.78Mg0.22Ni2.48 Mn0.09Al0.23Co0.47,Mm=82.3%La+17.7%Nd)was modified by electroless nickel plating to improve its electrochemical and kinetic properties.Alloy phase composition was analyzed by XRD,and the results show that the phase composition of the alloy has no change after electroless nickel plating.Electrochemical test results show that the alloy electrode has significantly increased discharge specific capacity after electroless nickel plating with the maximum327.7mA·h/g,and its cycle stability is also greatly improved with increased capacity retention rate from original 83.3% to 93.3% after 50charge/discharge cycles.Electroless nickel plating can improve alloy electrochemical properties,and thereby exchange current density i0,limiting current density iL,corrosion potential Ecorrand electrochemical reactivity of the alloy electrode are significantly improved.
