Method of making an electrochemical cell having resealable vent closure

Patent ·
OSTI ID:6495386
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.
