Abstract
A method for producing a battery cell having a plurality of film layers, a plurality of current collector layers, and at least one separator layer, with each current collector layer including a predetermined lead portion. The method includes the steps of providing at least one notch in each layer, and stacking the layers with the notches positioned with respect to one another to expose the predetermined lead portion of each current collector layer. A battery cell including an electrode having an area defined by a perimeter including an edge, a counter electrode having an area defined by a perimeter including an edge, and a separator having an area defined by a perimeter including an edge is also provided. The separator is sandwiched between the electrode and the counter electrode in a layered relationship with at least portions of the edges being continuous.
