HYDROGEN STORAGE ALLOY ELECTRODE

摘要

PURPOSE:To obtain a hydrogen storage alloy electrode having a long cycle life by covering the electrode with a conductive polymer. CONSTITUTION:Since a conductive polymer has electron conductivity, in a hydrogen storage alloy electrode covered with the thin film of the conductive polymer, electricity smoothly flows between a substrate and an active material on charge-discharge. The polymer has such binding capability that adhesion between active materials and between the active material and a substrate is surely retained. These features are not damaged by outside force such as cutting and bending in cell production and surely retained even if charge-discharge is repeated. A hydrogen storage alloy electrode having a long cycle life can be obtained.
