Abstract
The disclosed technology relates to electrodes of a battery cell. The electrodes include a current collector having a first non-rectangular shape, an active coated region having a second non-rectangular shape, an insulator coated region having a third non-rectangular shape, and an uncoated tab disposed adjacent to the insulator coated region. The insulator coated region is disposed along a periphery of the current collector along a plurality of sides or edges of the current collector providing several locations for the tab to be positioned.
