Abstract: The present disclosure is directed to methods of forming polyimide gels. The methods generally include forming a polyamic acid and dehydrating the polyamic acid with a dehydrating agent in the presence of water. The resulting polyimide gels may be converted to polyimide or carbon xerogels or aerogels. The methods are advantageous in providing rapid or even instantaneous gelation, which may be particularly useful in formation of beads comprising the polyimide gels. Polyimide or carbon gel materials prepared according to the disclosed method are suitable for use in environments containing 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 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 lithium transition metal phosphate and fluorophosphate materials in a conductive carbon matrix. The disclosed methods are advantageous in utilizing inexpensive reactants, can mitigate formation of impurities during the synthesis, providing a more homogenous product, and may provide cathode materials with enhanced tap density relative to prior lithium transition metal phosphates. The lithium transition metal phosphate and fluorophosphate materials prepared by the disclosed methods are intimately mixed with carbon within a continuous, three-dimensional conductive carbon matrix. The materials prepared according to the disclosed methods are suitable for use in environments involving electrochemical reactions, for example as cathode materials within a lithium-ion battery.
