Abstract
A packaged battery (60) is provided having a thin film lithium battery cell (62) sealed with a packaging foil or layer (67). The battery cell (60) includes a substrate (61) and an active cell (62) with an anode current collector (65) and a cathode current collector (64). The packaged battery is produced by heat sealing a packaging foil (67) to the exterior surfaces of the active cell (62).
