HYDROGEN ABSORBING ALLOY ELECTRODE

摘要

PURPOSE: To provide a hydrogen absorbing alloy electrode free from peeling off of an active material and separation of a current collector by molding a slurry-like material prepared by a kneading rechargeable hydrogen absorbing alloy powder together with prescribed materials in a specified process. CONSTITUTION: A slurry-like material 7 prepared by kneading rechargeable hydrogen absorbing alloy (example: LaNi3.8 Co0.7 Al0.5 ) powder together with a thickening agent (example: carboxymethylcellulose) and a binder (example: polytetrafluoroethylene) is molded together with a porous current collector 6 (example: a nickel expanded current collector obtained by forming a nickel sheet in rhombic network structure) in a molding mold frame 9.
