1. A method of fabricating an electrochemical cell, comprising the following steps:

  • forming an electrode cell stack and a metallic cell package having a base portion and a lid portion defining an enclosure, said cell package including a first section for receiving said cell stack and a second section having an inlet port which communicates with said first section;

    placing said cell stack into said enclosure in said first section;

    sealing said lid portion to said base portion around a periphery of said cell package to form a peripheral seam;

    introducing an electrolyte into said enclosure via said inlet port; and

    welding said lid portion to said base portion to form a first weld seam located between said first and second sections to seal off said first section from said second section.
