摘要: Abstract The effects of the relative Co and Mn content on electrochemical performance La 0.7 Mg 0.3 Ni 2 (Co+Mn) hydrogen storage alloys were investigated. crystal structure, discharge capacity cycle life evaluated. For all alloys, we found that higher content, larger is capacity. appropriate amount in can extend although have less than those with content. In addition, LaNi 3.87 1.13 phase appears 5 disappears replacement by Mn.
