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 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.

Abstract: Methods and compositions herein relate to producing an aluminosilicate aerogel. The method may include receiving a silica precursor in solvent, hydrolyzing the silica precursor to produce colloidal silica, introducing an aluminum compound to the colloidal silica to produce a colloidal aluminosilicate suspension, converting the aluminosilicate suspension to an aluminosilicate gel composition, and forming the aluminosilicate aerogel by extracting fluid.
