Abstract:The present investigation is aimed to study MmNi 5-type (Mm = Mischmetal) hydrogen storage alloys with composition, Mm 0•8 La 0•2 Ni 3•7 Al 0•38 Co 0•3 Mn 0•6−x Mo 0•02 Fe x (x = 0, 0•1, 0•2 and 0•3). The alloys are synthesized by radio-frequency induction melting. To study their electrochemical properties via measurements of discharge capacity, activation process, rate capability and cyclic stability, electrodes are fabricated using as-synthesized and annealed version of the alloys. The maximum discharge capa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
