PURPOSE:To accelerate an electrochemical hydrogen storage reaction during charging and restrain free generation of hydrogen gas and facilitate maintenance of a nickel-hydrogen storage battery by providing structure such that a water repellent resin layer is formed on the surface of an electrode base. CONSTITUTION:An application surface made from hydrogen storage alloy powder 2 and disposed on the upper portion of each electrode supporting body 1 is pressed and is then bent inward into the shape U independently and an application layer of the hydrogen storage alloy powder 2 is repressed between the electrode supporting bodies 1 from both sides of each electrode supporting body 1 to provide a stickingly integrated structure. Further, the electrode supporting bodies 1 are connected (welded) and fixed to each other at the upper opening of this electrode base so as to provide a connection fixing portion to form a non-sintered type hydrogen storage electrode. A lead plate is connected to the connection fixing portion 3 to constitute a negative electrode. A nickel-hydrogen storage battery is comprised of the negative electrode 4, a well-known nickel positive electrode 6, a separator 7 and an alkaline electrolyte 8. |
