Abstract
The housing of an electrochemical cell system has a vent passageway defined by a flared flange. The flange is flared outwardly with respect to the longitudinal axis of the passageway so that the opening of the vent passageway facing to the interior of the housing is smaller than the opening of the vent passageway facing to the exterior of the housing. An electrically insulating material, such as glass, is fused in the passageway to form a hermetic seal. The outwardly flared flange facilitates removal of the seal material responsive to excessive internal cell pressures so the cell can be vented safely.
