Abstract: Nanoporous carbon-based scaffolds or structures, and specifically carbon aerogels and their manufacture and use thereof. Embodiments include a sulfur-doped cathode material within a lithium-sulfur battery, where the cathode is collector-less and is formed of a binder-free, monolithic, polyimide-derived carbon aerogel. The carbon aerogel includes pores that surround elemental sulfur and accommodate expansion of the sulfur during conversion to lithium sulfide. The cathode and underlying carbon aerogel provide optimal properties for use within the lithium-sulfur battery.

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.
