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.

Devices, systems, and methods for controlling vent gases and ejecta from thermal runaway events in energy storage systems

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.

Systems and methods for mitigating thermal propagation in battery-based energy storage systems

This disclosure relates generally to aerogel technology. The disclosure relates more particularly, in various embodiments, to improved methods for producing aerogels and improved aerogel composites having a low compression set.
