The electroless plating method was used to coat the surface of the hydrogen storage alloy with metal palladium to improve the anti-oxidation and anti-chalking ability of the rare earth nickel-based hydrogen storage alloy. The effects of different palladium coating amount on the properties of the alloy were also studied. The results show that the effect of 10% (mass fraction) coating amount is ideal, which reduces the degree of pulverization of the hydrogen storage alloy and prolongs the life of the electrode
