摘要：

In this paper, phase constituent, hydrogen storage characteristics and electrochemical performances of composite TiCr1.8 + X wt.% LaNi5 alloys with different stoichiometry were investigated. X-ray diffraction (XRD) tests reveal that these alloys still remain Laves phase constituent despite the increase of LaNi5 content in alloys. Electrochemistry performance is improved whereas the maximum hydrogen storage capacity of pressure composition temperatures (PCT) test slightly decreases at the same time. One kind of alloy with capacity up to 55 mAh/g has been developed. (C) 2006 Elsevier B.V. All rights reserved.
