Hydrogen absorbing alloy electrode, manufacturing method thereof, and alkaline storage battery equipped with the hydrogen absorbing alloy electrode

摘要

After coating a hydrogen absorbing alloy slurry obtained by kneading a hydrogen absorbing alloy powder (12a), a polyethylene oxide (PEO) powder as a binder (12b), and a suitable amount of water (a solvent for binder) to both surfaces of a metal core plate (active material holder) made of a punching metal, the core plate is dried. Then, after removing the active material layer (13) from the core plate (11) by a means such as cutting and the like, a definite amount of water (a solvent for binder) is sprayed to the cut surface (the exposed surface of the core plate (11)) to attach the water to the cut surface followed by drying to provide a hydrogen absorbing alloy electrode (10), which is disposed at the outermost side of the electrode group.
