Abstract

Abstract: In ordertoimprovethe dischargecapacity of Ti2 Ni hydrogen storage alloy, the phases and effecton the property for Ti Nialloy with alittle La( La contentisbetween 5 25 wt% and12 62 wt%) were investigated in this paper. It is found that La exists in the form ofLaNi5 ,thesecond phase,in Ti Nialloy when La> 8 wt% . LaNi5 phasecaneffectivelyim provethe activity property and discharge capacity of Ti Ni alloy. While the soluble Ti inmain phase Ti2 Niisadverseto hydrogen adsorption desorption cycle and itshould be dimin ished .

Key words: Ti Ni La hydrogen storage alloy, phases, dischargecapacity
