Abstract: Nanoporous carbon-based scaffolds or structures, and specifically carbon aerogels and their manufacture and use thereof. Embodiments include a cathode material within a lithium-air battery, where the cathode is formed of a binder-free, monolithic, polyimide-derived carbon aerogel. The carbon aerogel includes pores that improve the oxygen transport properties of electrolyte solution and improve the formation of lithium peroxide along the surface and/or within the pores of the carbon aerogel. The cathode and underlying carbon aerogel provide optimal properties for use within the lithium-air battery.

Abstract: The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

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 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.
