    Abstract: The present disclosure relates to methods and systems to manage thermal runaway issues in energy storage systems. Exemplary embodiments include methods and systems having a compressible thermal barrier. The compressible thermal barrier is tailored in size (e.g., thickness, volume, etc.) to prevent thermal propagation between adjacent cells, modules and/or packs when a portion of an energy source has experienced a thermal event. The methods and systems mitigate thermal propagation such that a cell adjacent to a compromised cell (e.g., actively combusting cell) does not experience thermal runaway as it is shielded from dissipating heat and does not surpass a critical temperature. The present disclosure further relates to a battery module or pack with one or more battery cells and the compressible thermal barrier placed between adjacent cells.

    Abstract: The present disclosure relates to an insulation barrier for use in an electrical energy storage system, the insulation barrier comprising: at least one insulation layer; a support member surrounding at least a portion of the insulation layer; an encapsulation layer at least partially surrounding the insulation layer, wherein the encapsulation layer comprises a laminate film comprising an outer polymer layer, a rigid layer, and an inner polymer layer, wherein the inner polymer layer is in contact with the insulation layer and wherein the rigid layer is disposed between the outer polymer layer and the inner polymer layer; and wherein the encapsulation layer further comprises an extension portion extending beyond the support member in contact with an interior surface of a battery cell enclosure to form a seal with an interior surface of the battery cell enclosure.
