Pouch-type battery cells include a first and second pouch layer, one or more electrode pairs between the two pouch layers, each pair including an anode and cathode current collector, a peripheral seal defined by a peripheral seal path and joining the two pouch layers to form a pouch encasing the one or more electrode pairs, an anode tab electrically coupled to one or more anode current collectors within the pouch and a cathode tab electrically coupled to one or more cathode current collectors within the pouch each extend outward from the peripheral seal. The anode and/or cathode tab include one or more apertures disposed along the peripheral seal path such that a portion of the peripheral seal is formed between the first and second pouch layers within the one or more apertures. The tabs of multiple battery cells can be electrically coupled via busbars to form a battery pack.
