Original Abstract Submitted

A prismatic battery cell has a cell case, an electrolyte, and a sealing member. The cell case has an interior cavity and a fill port. The fill port has an inner surface. The fill port is in fluid communication with an ambient environment and the interior cavity. The electrolyte is disposed in the interior cavity through a one-way valve in the sealing member. The sealing member is disposed in the fill port. The sealing member has an exterior sealing surface that forms a fluid seal with the inner surface of the fill port. The sealing member has a valve formed therein. The valve has an open position for allowing the electrolyte to enter the interior cavity and a closed position to prevent the electrolyte from exiting the interior cavity. Moreover, the valve allows for degassing of the battery cell after the formation process.
