mg hydrogen storage alloy in content. The electrode was then tested at 25 ℃ in an open-cell with an electrolyte of KOH (6 mol/L) and a positive electrode of Ni(OH)2/NiOOH. The discharge capacity... characteristics Fig.1 shows the XRD patterns of the LaNi4.2-xCo0.6- MnxAl0.2 (x=0-0.2) hydrogen storage alloys. It can be seen that the substitution of Ni by Mn does not change the crystal structure which consist......
