- Abstract
The AB5-type hydrogen storage alloys La0.7Ni2.5Co0.9-xMn0.1Alx were prepared by magnetic induction melting. The structure and the electrochemical properties of alloys were also investigated using X-ray powder diffraction technique and various electrochemical measurements. All the alloys are mainly composed of the LaNi5 phase with a CaCu5-type hexagonal structure. The alloy electrodes deliver good electrochemical hydrogen storage properties. The maximum discharge capacities of La0.7Ni2.5Co0.9Mn0.1 alloy at room temperature and low temperature are 355.2 and 378.3 mAh/g, respectively. Although the discharge capacities the alloy electrodes decrease with the increasing Al content, the cycling stabilities are improved.
