Abstract
A series of (Sc 1− x Ti x )Ni alloys and their hydrides (Sc 1− x Ti x )NiH y , where x =0, 0.1, 0.3, 0.5, and y =2.9, 2.58, 2.23 and 1.55, have been prepared. The ability to store hydrogen gradually decreases with increasing Ti content in line with the reduction of the unit cell volume from 32.16 Å 3 for ScNi to 29.68 Å 3 for (Sc 0.5 Ti 0.5 )Ni. The electrochemical discharge capacity, however, varies in a more complex manner with (Sc 0.7 Ti 0.3 )Ni composition displaying the highest value of 231 mAh/g. The discharge capacity losses after 10 electrochemical charge–discharge cycles also vary non-linearly between 46% for (Sc 0.9 Ti 0.1 )Ni and 5% for (Sc 0.5 Ti 0.5 )Ni.
