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 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: 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.

Abstract: Described herein are insulating structures that include at least one microporous layer including a plurality of pores, a porous layer adjacent to the microporous layer, and a monolithic aerogel structure extending through the plurality of pores of the microporous layer and through at least part of the porous layer. The microporous layer filters aerogel dust from cracked or damaged aerogel within the scaffold, slowing or preventing loss of dust from the insulating structures.
