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: Silicon nanoparticles and methods for preparation of silicon nanoparticles are provided. Embodiments include a method for grinding silicon. Methods include providing silicon material, providing a grinding liquid including a polar solvent, and grinding the silicon material in the presence of the grinding liquid to yield silicon nanoparticles. Grinding the silicon in the presence of the grinding liquid can chemically functionalize the silicon material as the nanoparticles are formed to provide stable chemically functionalized nanoparticles.

Abstract: Methods and compositions herein relate to producing an aluminosilicate aerogel. The method may include receiving a silica precursor in solvent, hydrolyzing the silica precursor to produce colloidal silica, introducing an aluminum compound to the colloidal silica to produce a colloidal aluminosilicate suspension, converting the aluminosilicate suspension to an aluminosilicate gel composition, and forming the aluminosilicate aerogel by extracting fluid.
