METHOD OF MANUFACTURING HYDROGEN STORAGE ALLOY COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method of enhancing dissolving efficiency at the time of putting a negative electrode active material or a negative electrode active material principal composition recovered from a used nickel-hydrogen battery into the molten alloy of a negative electrode active material constituent element and heat-dissolving the same.

SOLUTION: Aluminum is added into a molten alloy simultaneously with a negative electrode principal recovered matter or sequentially, and the dissolving efficiency of the negative electrode active material or the negative electrode active material principal composition can be enhanced.
