NOVELTY - An alkaline storage battery (1) consists of an electrolyte solution, a positive electrode component (13), and a negative electrode component (15). The electrode binder contains an organic-inorganic hybrid material obtained by hybridizing an acrylic type-silicone type-urethane type copolymer having an acrylic type polymer chain portion, a urethane type polymer chain portion, and a silicone type polymer chain portion which couples the acrylic type polymer chain portion and urethane type polymer chain portion, and silica.    USE - Alkaline storage battery e.g. nickel hydride secondary battery (claimed) used in motor vehicles and electric trains.    ADVANTAGE - The alkaline storage battery has excellent long-term charge-discharge cycle performance, and low impact on human body and environment. The battery can be manufactured economically, due to the fact that binders which are easy to handle in the manufacturing process and have excellent adhesiveness and long-term durability are used for the electrodes.    DETAILED DESCRIPTION - An alkaline storage battery consists of an electrolyte solution containing an alkali type aqueous solution, a positive electrode component formed by applying a positive mix containing an active material to a substrate, and a negative electrode component formed by applying a negative mix containing an active material to a substrate. The positive mix and/or negative mix are aqueous and one-component crosslinked materials free of elemental fluorine. The electrode binder contains an organic-inorganic hybrid material obtained by hybridizing an acrylic type-silicone type-urethane type copolymer having an acrylic type polymer chain portion, a urethane type polymer chain portion, and a silicone type polymer chain portion which couples the acrylic type polymer chain portion and urethane type polymer chain portion, and silica. An INDEPENDENT CLAIM is included for electrode binder.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the alkaline storage battery.
