摘要： The present disclosure relates to materials and systems to manage thermal runaway issues in energy storage systems. Exemplary embodiments include an insulation layer that is encapsulated to form an insulation barrier. A support member is placed around at least a portion of an insulation layer. The support member provides a support for the insulation layer, allowing the insulation layer to be easily encapsulated and installed in a battery module or pack.

摘要： 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.

摘要： The present disclosure relates to materials and systems to manage thermal runaway issues in energy storage systems. Exemplary embodiments include an insulation layer that is encapsulated to form an insulation barrier. A particle capture layer is included in the insulation barrier. The particle capture layer captures particles released from the insulation barrier during compression of the insulation barrier.

摘要： The present disclosure relates to materials and systems to manage thermal runaway issues in battery modules. In exemplary embodiments, a battery module includes battery cells separated by spacer elements. To mitigate thermal runaway issues, spacer elements may be extended to the interior surface of the enclosure. A seal is formed between the spacer elements and the interior wall to form a thermal barrier between adjacent battery cells.

摘要： The present disclosure relates to materials and systems to manage thermal runaway issues in energy storage systems. Exemplary embodiments include a thermal barrier material that includes multiple layers. The multilayer thermal barrier material includes at least one insulation layer, at least one compressible pad, and optional one or more layers that have favorable heat-dissipating properties, have favorable fire, flame and/or abrasion-resistance properties, have favorable performance for use as thermal barriers. The present disclosure further relates to a battery module or pack with one or more battery cells and the multilayer thermal barrier material placed in thermal communication with the battery cell.
