Abstract
The studies have been carried out on utilizing Ml(NiAl)(5)-based alloy s as a low cost negative battery electrode. The replacement of nickel by copper improved the cycle lifetime to some extent without a decreas e in capacity. Using Ml(NiAlCu)(5) alloys, hydrogen storage alloys wit h good overall characteristics and low cost were obtained through subs tituting cobalt or silicon for nickel. The discharge capacity was furt her increased by increasing the lanthanum content in lanthanum-rich mi schmetal.
