Abstract

Abstract The electrochemical performance of a Ti 46Ni 45Nb 9 electrode in different solutions has been studied. The Ti 46Ni 45Nb 9 electrode can absorb/desorb hydrogen in 3 M KOH aqueous and lithium in non-aqueous solution (1 M LiClO 4 dissolved in a 50/50 vol.% (v/o) mixture of ethylene carbonate and diethyl carbonate), respectively. It is assumed that lithium and hydrogen are incorporated in the Ti 46Ni 45Nb 9 electrode in saturated LiCl+LiOH solution and result in a more positive potential value of hydrogen desorption and an abnormal discharge curve.
