Alkaline cell with double collector positive, negative, and third terminal connections
An alkaline cell is described wherein at least a pair of flat electrode elements of opposite polarity have a porous separator containing the alkaline electrolyte interposed between them. The elements are arranged in the form of a conventional electrode stack assembly. The electrode assembly is enclosed within a sealed, liquid-impervious plastic film envelope having a positive, negative, and third terminal connection in the walls thereof. Each terminal connection comprises flat internal and external current collectors disposed adjacent to the inner and outer sides, respectively, of the walls overlying openings therein. The collectors are tightly adhered to the respective sides of the walls by thin layers of an adhesive sealant which is nonwettable by the alkaline electrolyte. Means are provided for making electrical connection between the current collectors through the openings in the walls of the envelope. 7 figures.
