NOVELTY - A nickel-hydride storage battery comprises separator disposed between positive electrode and negative electrode, and alkaline electrolyte. The negative electrode comprises negative electrode mixture layer containing hydrogen-absorbing alloy powder capable of absorbing and desorbing hydrogen electrochemically and water-repellent layer on surface of negative electrode mixture layer. The separator comprises main layer having nonwoven fabric structure made of fiber and composite layer formed on surface of main layer. The composite layer is in contact with water-repellent layer.    USE - Nickel-hydride storage battery e.g. cylindrical-type nickel-hydride storage battery is used for assembled battery (claimed) for electric vehicle.    ADVANTAGE - The nickel-hydride storage battery has excellent cycle characteristics and high capacity. The increase of internal pressure of nickel-hydride storage battery and leakage of alkaline electrolyte is suppressed.    DETAILED DESCRIPTION - A nickel-hydride storage battery comprises a positive electrode, a negative electrode, a separator disposed between positive electrode and negative electrode, and an alkaline electrolyte. The negative electrode comprises both a negative electrode mixture layer containing a hydrogen-absorbing alloy powder capable of absorbing and desorbing hydrogen electrochemically and a water-repellent layer containing polymer (A) comprising tetrafluoroethylene as monomer units formed on the surface of the negative electrode mixture layer. The separator comprises both a main layer having a nonwoven fabric structure made of fiber and a composite layer formed on the surface of the main layer. The composite layer is in contact with the water-repellent layer. The composite layer comprises fibers which continue from the nonwoven fabric structure and polymer (B) comprising tetrafluoroethylene as monomer units. The surface of the composite layer has a contact angle of 10-80 degrees with respect to water. An INDEPENDENT CLAIM is included for assembled battery.
