An alkaline battery and a method of producing an alkaline battery that includes a negative electrode gel in which a negative electrode active material made of a zinc alloy and a binder are dispersed in an alkaline aqueous solution. Ultrafine microfibrils form the binder.

Alkaline battery and method of producing negative electrode gel for alkaline battery

An alkaline battery is made by press-fitting a plurality of tubular positive electrode pellets inside of an open end of a cylindrical positive electrode can. The press-fitting is performed in such a manner as to stack the positive electrode pellets coaxially inside of and in contact with the positive electrode can, with gaps between adjacent positive electrode pellets. A separator is disposed inside of the tubular pellets, and a negative electrode mixture is placed inside of the separator. A negative electrode current collector is inserted into the negative electrode mixture, and the opening at the open end of the positive electrode can is sealed with a negative electrode terminal plate.
