Abstract: The disclosed technology relates to a battery utilizing a dampening layer to prevent a failure of the battery. The battery includes an enclosure, a set of electrodes enclosed within the enclosure, and a dampening layer disposed within the set of electrodes. The dampening layer partitions the set of electrodes into a first subset of electrodes and a second subset of electrodes. The dampening layer is configured to absorb a mechanical impact on the enclosure to prevent a failure of at least one of the first subset of electrodes and the second subset of electrodes. The dampening layer may be formed at least one of a polymer, metal, and ceramic.

Abstract: The disclosed technology relates to a set of battery tabs. The battery tabs include a first tab forming an elongated member, a second tab forming an elongated member, and a unitary seal surrounding a portion of the respective elongated members of the first tab and the second tab. The unitary seal spaces the first tab apart from the second tab to create a gap between the first tab and the second tab. The first tab and second tab each connect to respective electrodes enclosed within a pouch of a battery cell to allow the cell's energy to be transferred to an external component.
