Abstract: Nanoporous carbon-based scaffolds or structures, and specifically carbon aerogels and their manufacture and use thereof are provided. Embodiments include a silicon-doped anode material for a lithium-ion battery, where the anode material includes beads of a polyimide-derived carbon aerogel. The carbon aerogel may further include silicon particles and accommodates expansion of the silicon particles during lithiation. The anode material provides optimal properties for use within the lithium-ion battery.

Abstract: The present disclosure is directed to methods of forming polyamic acid and polyimide gels in water. The resulting polyamic acid and polyimide gels may be converted to aerogels, which may further be converted to carbon aerogels. Such carbon aerogels have the same physical properties as carbon aerogels prepared from polyimide aerogels obtained according to conventional methods, i.e., organic solvent-based. The disclosed methods are advantageous in reducing or avoiding costs associated with use and disposal of potentially toxic solvents and byproducts. Gel materials prepared according to the disclosed methods are suitable for use in environments involving electrochemical reactions, for example as an electrode material within a lithium-ion battery.

Abstract: The present disclosure is directed to methods of forming polyamic acid, polyamic acid metal salt, and polyimide gels under aqueous conditions, the methods utilizing water-soluble carbonate or bicarbonate salts. These gels may be converted to aerogels or xerogels, which may further be converted to carbon aerogels or xerogels. Such carbon aerogels or xerogels have the same physical properties as carbon aerogels or xerogels prepared from polyimide aerogels obtained according to conventional methods, i.e., organic solvent-based methods.
