Abstract

PURPOSE:To obtain an extremely thin battery by constituting the battery by the combination of a positive nickel can a part of which is made into an active material, a separator, and a negative zinc can also serving as a negative active material. CONSTITUTION:A thin battery is constituted of a positive can 1 which is made of nickel and the inner wall of which is made into a positive active material layer 2, a separator 4 consisting of a porous membrane 5 made of polypropylene and impregnated with alkaline electrolyte and a non-woven cloth 6 made of nylon, and a negative can 3 which is made of zinc and also serves as a negative active material. For instance, a positive can 1 is prepared by coating a nickel plate of 0.2mm. thickness, except the part which is made into an active material, with an epoxy resin, and immersing the nickle plate in a sulfuric acid solution of high concentration for two hours. As a result, the surface of the nickel plate becomes rough, and eluted nickel turns into Ni(NO3)2, which exists near the nickel plate. After that, the nickel plate immersed in the solution is gradually heated to 30 deg.C to make Ni(NO3)2 to be deposited in the concaves and convexes of the rough surface of the nickel plate. Next, the resin coat is removed, before the entire nickel plate is subjected to formation so as to make the entire surface of the plate to be converted into Ni(OH)2. By the means mentioned above, a extremely thin battery can be obtained.
