Abstract: The present invention provides a fiber-reinforced aerogel material which can be used as insulation. The fiber-reinforced aerogel material is highly durable, flexible, and has a thermal performance that exceeds the insulation materials currently used. The fiber-reinforced aerogel insulation material can be as thin as 1 mm or less, and can have a thickness variation as low as 2% or less. Also provided is a method for improving the performance of a battery by incorporating a reinforced aerogel material into the battery. Further provided is a casting method for producing thin fiber-reinforced aerogel materials.

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 can provide an aerogel composite. The aerogel composite comprises at least one base layer having a top surface and a bottom surface, the base layer comprising a reinforced aerogel composition which comprises a reinforcement material and a monolithic aerogel framework, a first facing layer comprising a first facing material attached to the top surface of the base layer, and a second facing layer comprising a second facing material attached to the bottom surface of the base layer. At least a portion of the monolithic aerogel framework of the base layer extends into at least a portion of both the first facing layer and the second facing layer.
