Abstract
The microstructure, hydriding performance, and electrochemical properties of LaNi4.0Al0.2Fe0.4Cu0.4-xSnx (x = 0 ∼ 0.4) hydrogen storage alloys prepared by casting were investigated using XRD, SEM, pressure-composition isotherms, and electrochemical measurements. Substitution of Sn for Cu leads to the precipitation of LaNiSn phase. With increasing amount of tin substitution, cell volume, plateau pressures, and discharge capacities of the alloys decrease, whereas the cycle life of the alloys improves.
