| Abstract: | The effects of electroless nickel plating on the particles morphology and the electrochemical properties of low-Co hydrogen storage alloy were investigated. The results showed that the electroless nickel plating could increase the discharge capacity, 1 C discharge properties and cycle stability obviously, and could also improve the activation. The SEM morphology showed that hydrogen reaction was found during the process of nickel plating. The mechanism of nickel plating effects on the electrochemical properties of low-Co hydrogen storage alloy was discussed. |
