Patent ID: 7651546

Claim:
A method for manufacturing high-purity magnesium-nickel hydrogen storage alloy, comprising steps of: heating a raw material of magnesium in an inert gas, and melting the raw material of magnesium to a magnesium liquid; adding nickel powders to the magnesium liquid, and stirring and heating the magnesium liquid mixed with the nickel powders for melting the nickel powders in the magnesium liquid; producing a magnesium-nickel liquid after the nickel powders are melted in the magnesium liquid; controlling the temperature of the magnesium-nickel liquid to fall within a temperature range, and the magnesium-nickel liquid precipitating a solid-state magnesium-nickel hydrogen storage alloy; and separating the residual liquid from the precipitated solid-state magnesium-nickel hydrogen storage alloy, and producing the solid-state magnesium-nickel hydrogen storage alloy, and recovering a separated residual liquid.
