Abstract: An electrochemical cell has an electrode assembly comprising an anode active material contacted to the inner surface of a casing, and a cathode active material contacted to a current collector connected to the terminal pin of a GTMS supported by the casing. The cathode is wrapped in a separator having a first lateral edge and a spaced-apart second lateral edge. The separator first and second lateral edges extend from a lower edge to an opposite upper edge. With the separator wrapped around the cathode, a lower portion of the separator first and second lateral edges and the lower edge are sealed to cover a cathode lower end, and an upper portion of the separator first and second lateral edges and the upper edge are sealed to cover a cathode upper end, but the first and second lateral edges in an intermediate section are unsealed. An electrolyte activates the electrode assembly.

Abstract: A miniature electrochemical cell of a primary or a secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper closure plate. The upper plate has a sealed electrolyte fill port. A current collector having an opening aligned with the fill port contacts an inner surface of the upper plate. An anode active material contacts the lower plate, and a cathode active material contacts the upper closure plate. A dielectric material coats the lower open end of the annular sidewall and a portion of the inner surface of the sidewall. A glass seals the dielectric material to the lower plate. An electrolyte contacts the electrode assembly. The cathode active material contacting the current collector has an opening aligned with the current collector opening and the electrolyte fill port.

Abstract: A miniature electrochemical cell of a primary or secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper lid. The lid has a sealed electrolyte fill port. At least one electrolyte channel in the inner surface of the lid extends radially from the fill port and outwardly beyond an outer peripheral edge of the current collector. A current collector contacts an inner surface of the lid with a first electrode active material contacting the current collector. An opposite polarity active material contacts the lower plate. A dielectric material coats the lower open end of the annular sidewall and a portion of the inner surface of the sidewall. A glass seals the dielectric material to the lower plate. An electrolyte activates the electrode assembly.
