Abstract: The current disclosure provides reinforced aerogel compositions that are durable and easy to handle, have favorable performance in aqueous environments, have favorable insulation properties, and have favorable, reaction to fire, combustion and flame-resistance properties. Also provided are methods of preparing or manufacturing such reinforced aerogel compositions. In certain embodiments, the composition has a silica-based aerogel framework, reinforced with an open-cell macroporous framework, and includes one or more fire-class additives, where the silica-based aerogel framework comprises at least one hydrophobic-bound silicon and the composition or each of its components has desired properties.

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. The first facing material and the second facing material can each comprise or consist essentially of elastic fibers such as spandex, nylon, lycra, elastane, or combinations thereof.

Abstract: The present invention provides aerogel materials based on imidazoles and polyimidazoles. The polyimidazole based aerogel materials can be thermally stable up to 500° C. or more, and can be carbonized to produce a carbon aerogel having a char yield of 60% or more, specifically 70% or more. The present invention also provides methods of producing polyimidazole based aerogel materials by reacting at least one monomer in a suitable solvent to form a polybenzimidazole gel precursor solution, casting the polybenzimidazole gel precursor solution into a fiber reinforcement phase, allowing the at least one gel precursor in the precursor solution to transition into a gel material, and drying the gel materials to remove at least a portion of the solvent, to obtain an polybenzimidazole-based aerogel material.

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.
