Abstract: A resilient battery cell is provided that includes an electrode and an electrolyte hermetically sealed within a pouch. The pouch includes layers of heat-resistant and resilient materials coupled together by a thermoplastic seal. A conductive tab electrically coupled to the electrode and for electrically coupling of the battery cell to other cells and/or a battery terminal extends through and is hermetically sealed by the sealant. The battery cell may further include supplemental layers external the pouch for providing structural integrity, a vapor barrier, improved fire safety, and other benefits.
