Abstract: A non-resealable vent closure for galvanic cells, such as nonaqueous cells, which comprises a member force-fitted within a liner disposed adjacent the wall defining an orifice and wherein a sealant is disposed between the wall defining the orifice and the liner so as to prevent electrolyte leakage at the interface of the liner and the wall defining the orifice.

Abstract: A resealable vent closure for galvanic cells, such as non-aqueous oxyhalide cells, which comprises a castellated type of cap employed to compress and retain a resilient deformable member over a vent orifice in the cell's housing such that the compressed resilient deformable member will form a normally tight seal at the vent orifice which will vent and reseal after a predetermined pressure build up within the cell. The invention is also directed to a method for assembling an electrochemical cell, such as a nonaqueous oxyhalide cell, with the above-described resealable vent closure.

Abstract: A non-resealable vent closure for galvanic cells, such as nonaqueous oxyhalide cells, which comprises a member force-fitted within a vent orifice and wherein a corrosion-resistant material which is not an integral part of the force-fitted member is disposed between the wall defining the vent orifice and the force-fitted member so as to predictably insure venting after a predetermined gas pressure build-up within the cell.

Abstract: A safety blow-out vent closure for galvanic cells, such as nonaqueous oxyhalide cells, which comprises the employment of a conductive tubular member secured to the cell's housing and surrounding a vent orifice in the cell's housing and wherein a deformable member is force-fitted in said vent orifice and adapted to at least partially be ejected from the vent orifice upon the build up of a predetermined internal gas pressure within the cell. The invention is also directed to a method for assembling an electrochemical cell with the above-described safety vent closure.

Abstract: A nonaqueous cell employing a liquid cathode, such as an oxyhalide, an active anode, such as lithium, a cathode collector, such as carbon and/or graphite, and a separator between said anode and said collector and wherein said separator comprises a uniform mixture of 85 to 95 weight percent glass fibers having a substantially uniform size and 15 to 5 weight percent binder, such as polyvinyl alcohol.
