ZINC/AIR CELL

摘要

A zinc/air depolarized button cell having an anode casing and cathode casing in the form of cans each having an open end and opposing closed end with integral side walls therebetween. An improved insulator seal ring is inserted over the anode casing side walls. The improved insulator seal ring has protrusions emanating from the surfaces of the insulating ring side walls. The protrusions are preferably integrally formed during molding of the insulating seal ring, but may be separately applied. The protrusions compress during application of radial forces to the cathode casing during the crimping of the cathode casing side walls over the anode casing side walls with said insulator ring therebetween. This provides a tighter, more durable seal, at the interface between anode casing and insulator side walls and also between cathode casing and insulator side walls. The claims relate to a zinc/air depolarized cell in which the separator is bonded to the cathode using a glue comprising a cross-linked poly vinyl alcohol.
