Document Type and Number:
Japanese Patent JP2574016
Kind Code:
B2
Abstract:
PURPOSE:To improve the anticorrosive property of a cathode container by forming the cathode container to form a cathode chamber with an aluminum alloy such as an aluminum-manganese-chromium alloy or an aluminum- manganese alloy, and providing an anticorrosive membrane of a chromium plating layer at the inner surface of the container. CONSTITUTION:A cathode container 1 to form a cathode chamber R2 is formed of an aluminum alloy such as an aluminum-manganese-chromium alloy or an aluminum-manganese alloy, and an anticorrosive membrane of a chromium plating layer is provided at the inner surface of the container 1. That is, while the cathode container 1 is formed of an aluminum alloy, an anticorrosive membrane of a chromium plating layer whose cracking density is less increased even though the temperature is raised near the operational temperature of the cell is provided. As a result, the cathode container 1 is made lightweight, the anticorrosive property is improved, and the cell can bear the service for a long period.
