Abstract: A method of manufacturing an energy storage device for a medical device that includes creating an aperture in a case. The aperture includes an inner surface. The method also includes introducing an electrolyte into the case through the aperture and moving a sealing member into the aperture. The sealing member includes an outer surface. Furthermore, the method includes sealing the aperture only with the sealing member and creating a substantially hermetic seal between the inner surface of the aperture and the outer surface of the sealing member.

Abstract: A method of manufacturing an energy storage device for a medical device includes enclosing a cell assembly in a case. The case includes a filling aperture. The filling aperture includes an inner surface that is integral to the case so as to be monolithic. The case is free of a separate fill port tube. Moreover, the method includes introducing an electrolyte into the case through the filling aperture and hermetically sealing the filling aperture to form a first seal of the filling aperture that is free of a filler material. The method additionally includes hermetically sealing the sealing member to the case to form a second seal of the filling aperture.

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.
