PURPOSE:To retard transmission of water vapor from a container to prevent deterioration of battery performance by embedding a metal inside a synthetic resin container. CONSTITUTION:In order to prevent transmission of water vapor from a container 4, an aluminum plate 5 is embedded inside the container made of, for example, ABS resin. By using this container, decrease in electrolyte is minimized. Therefore, performance deterioration of a battery caused by electrolyte decrease is prevented. |
