The Influence of Coated Palladium on the Property of Hydrogen Storage Alloy

To improve the ability of anti oxidation and anti-pulverization of rare-earth/nickel base hydrogen storage alloy, palladium was coated by electroless plating, and the influence of the coated palladium on the properties of the alloy with different Pd contents was investigated.The results show that the negative electrode made of the coated alloy with 10%(w) Pd has better anti-pulverization ability and longer circle life.
