Mechanisms and methods for pressurized fluid injection and sealing into containment vessels using a divided valve mechanism are disclosed. The invention describes designs and methods in which a valve may be plugged by an actuator, and then the valve and actuator are disjoined, allowing the containment vessel to then be sealed but without the additional mass or volume of the actuation mechanism and without fluid loss from the containment vessel.

Mechanisms and methods for pressurized fluid injection and sealing

A cap assembly is disclosed that creates a gas-tight seal with a cell can housing. The cap assembly has an outer surface, an inner surface and a perimeter edge. The cap assembly further includes an electrolyte injection port forming a port opening between the outer surface and the inner surface, a vent constructed to form a vent opening from the inner surface to the outer surface when a vent pressure differential is achieved between an outer surface pressure and an inner surface pressure. The vent is positioned (a) concentric to the electrolyte injection port, and (b) closer to the perimeter edge than the position of the electrolyte injection port.
