Embodiment Construction
[0009] surface The composition of the hydrogen storage alloy
[0010]
[0011] According to the alloy composition ratio, the rare earth element is in the form of lanthanum-rich rare earth alloy, the element Sm is added in the form of simple substance, and the purity of other metals is above 99.5%. The prepared raw materials are vacuumed to 0.05Pa in a vacuum quenching furnace, and then passed Argon protection, pressure about 0.05MPa, melting and throwing into 0.05~0.1mm hydrogen storage alloy sheet, heat treatment at 800~1050°C for 4~8 hours, after cooling, mechanical ball milling and sieving , to obtain hydrogen storage alloy powder with particle size less than 0.08mm.
[0012] According to the above hydrogen storage alloy powder preparation process, the hydrogen storage alloy powder Examples 1 to 6 with the composition shown in Table 1 were obtained, and the comparative example used commercially available hydrogen storage alloy powder for power nickel-hydrogen batter...
