چکیده
The electrochemical performance of a Ti Ni Nb electrode in different solutions has been studied. The Ti Ni Nb electrode can 46 45 9 46 45 9 Ž Ž . absorbrdesorb hydrogen in 3 M KOH aqueous and lithium in non-aqueous solution 1 M LiClO dissolved in a 50r50 vol.% vro 4 . mixture of ethylene carbonate and diethyl carbonate , respectively. It is assumed that lithium and hydrogen are incorporated in the Ti Ni Nb electrode in saturated LiClqLiOH solution and result in a more positive potential value of hydrogen desorption and an 46 45 9 abnormal discharge curve. q 1998 Elsevier Science S.A.

Effects of Nb and I’d 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.
