| 简介 |
An enclosed type nickel-hydrogen battery provided with high output characteristics with excellent charge/discharge cycle characteristics retained, and a production method thereof. A hydrogen storing electrode as an electrode is used that uses hydrogen storing alloy powder consisting of a rear-earth element and a metal element including Ni and excluding rear-earth element, and having a specific equilibrium hydrogen dissociation pressure, a specific mass saturation magnetization, and a specific ratio between a rear-earth element and a non-rear-earth element. The hydrogen storing electrode is used, and at least one welding point out of a welding point between the inner surface of a sealing plate and a collector lead and a welding point between the collector lead and an upper collector plate is welded by energizing between an anode terminal and a cathode terminal after sealing by means of an external power supply to produce an enclosed type nickel-hydrogen battery. |
