PROBLEM TO BE SOLVED: To substantially shorten the time required for the whole production of batteries, reduce contamination caused by oxygen, and provide large discharging capacity. SOLUTION: A hydrogen storage alloy 3 is melted in vacuum or in an inert gas atmosphere, quenched by a single roll or twin roll rolling process to manufacture a hydrogen storage alloy film 5. Immediately after it the hydrogen storage alloy film 5 is pressed against a supporting body 7 to form a secondary battery negative electrode 10. |
