Abstract
Methods and battery cells formed thereby are provided that minimize issues with an exposed metallic layer at the peripheral edge of a flexible laminate forming a battery cell pouch. Sealing the periphery of the pouch is optimized projecting terminals of the electrochemical cell through perforations in the flexible laminate at a folded edge thereof. The folded edge does not present an exposed metallic layer and does not require a sealing material or use of sealing operation complicated by the terminals.
