ABSTRACT:
An electrochemical cell including a cell enclosure, a fill tube, a ball, a closing button, an anode, a cathode, and an electrolyte. The cell enclosure defines an internal volume and includes a cover forming a fillport through hole. The fill tube is separately formed, and defines a leading section, a trailing section, and a passageway. The leading section is secured within the fillport through hole. The ball is sealingly secured within the passageway. The closing button is also separately formed, and is sealingly secured within the fillport through hole adjacent the leading section of the fill tube. The anode, cathode, and electrolyte are maintained within the internal volume. By configuring the fill tube such that the leading section thereof is secured within the fillport through hole, an overall extension of the fill tube relative to the internal volume is greatly reduced, thereby maximizing a volumetric efficiency.
