Effects of Nb and Pd on the electrochemical properties of a Ti-Ni hydrogen-storage electrode

The effects of Nb and Pd on the electrochemical properties of a Ti-Ni hydrogen-storage electrode are studied. The results show that adding Pd or Nd to the alloy can slow down the rate of decay of the exchange current during charge-discharge cycling and is also useful in increasing the discharge capacity and cycle life of Ti-Ni electrodes.
