FLAT ALKALINE CELL WITH DOUBLE COLLECTOR POSITIVE, NEGATIVE AND THIRD TERMINAL CONNECTIONS

摘要

FLAT ALKALINE CELL WITH DOUBLE COLLECTOR POSITIVE NEGATIVE AND THIRD TERMINAL CONNECTIONS A flat alkaline cell is described wherein at least a pair of flat electrode elements of opposite polarity having a porous separator containing the alkaline electrolyte interposed therebetween are arranged in the form of a conventional electrode stack assembly, and wherein the electrode assembly is enclosed within a sealed, liquid-impervious plastic film envelope having a positive, negative and a third terminal connection in the walls thereof, each terminal connection comprising flat internal and external current collectors disposed adjacent to the inner and outer sides respectively of the walls overlying openings therein, the collectors being tightly adhered to the respective sides of the walls by thin layers of an adhesive sealant which is non-wettable by the alkaline electrolyte. Means are provided for making electrical connection between the current collectors through the openings in the walls of the envelope. S P E C I F I C A T I O N
