Abstract
Exemplary battery cell designs, such as those for use within electrified vehicle traction battery packs, for example, may include an electrode assembly that includes a plurality of current collector tabs. The current collector tabs may be arranged in one or more tab groupings when the electrode assembly is positioned in a folded configuration. The current collector tabs of the one or more tab groupings may be joined together to establish an enlarged current collector tab that is larger than any individual one of the current collector tabs of the one or more tab groupings. The enlarged current collector tab is an optimized tab configured to reduce internal resistance, reduce heat buildup, and increase the power capability of the battery cell.
