Claim 0:
1. A method for manufacturing a battery cell, the method comprising:
placing a pin within an annular channel, the annular channel comprising an outer ring and an inner sidewall;
forming an insulator between the pin and inner sidewall of the annular channel using glass, wherein the pin extends through the insulator;
sliding the annular channel within an opening disposed on a terraced portion of an enclosure, the terraced portion having a reduced thickness with respect to a thickness of another portion of the enclosure, the enclosure configured to enclose a set of layers, the set of layers comprising a cathode layer, an anode layer, and a separator layer disposed between the cathode layer and the anode layer;
welding the outer ring of the annular channel to the enclosure along a periphery of the opening to create a hermetic seal;
welding a cathode tab extending from the cathode layer to the pin;
welding an anode tab extending from the anode layer to the enclosure;
hermetically sealing the set of layers within the enclosure; and
filling the enclosure with electrolyte.
