Abstract

A metal foil laminate package for an electrochemical cell has a multilayered structure (32, 34) comprising a metal foil (40) sandwiched between layers of a thermoplastic (38) and a heat-sealable polymer (42). An electrically conducting tab (28) extends from the cell and has a layer of insulative tape (29) disposed on both sides of the tab. Apertures (50,52,60,62) formed through the various layers of the package expose both sides of the tab, providing sites for subsequent welding of the tab to external circuitry.
