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

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.
