The invention provides a battery cell including an electrode having an area (18) defined by a perimeter (20) including an edge (22), a counter electrode having an area (24) defined by a perimeter (46) including an edge (28), and a separator having an area (30)defined by a perimeter (32) including an edge (34). The separator is sandwiched between the electrode and the counter electrode in a layered relationship with at least portions of the edges being contiguous. The separator and one of the electrode and the counter electrode each include a first notch (44) in the edge exposing a portion of the other of the electrode and counter electrode. The separator and the other of the electrode and the counter electrode each include a second notch (46) in the edge exposing a portion of the one of the electrode and the counter electrode. A method of 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, is also provided. The method includes the steps of: providing at least one notch in each layer, and stacking the layers with the notches arranged with one another to expose the predetermined lead portion of each current collector layer. |
