Abstract: The present invention provides aerogel materials based on imidazoles and polyimidazoles. The polyimidazole based aerogel materials can be thermally stable up to 500° C. or more, and can be carbonized to produce a carbon aerogel having a char yield of 60% or more, specifically 70% or more. The present invention also provides methods of producing polyimidazole based aerogel materials by reacting at least one monomer in a suitable solvent to form a polybenzimidazole gel precursor solution, casting the polybenzimidazole gel precursor solution into a fiber reinforcement phase, allowing the at least one gel precursor in the precursor solution to transition into a gel material, and drying the gel materials to remove at least a portion of the solvent, to obtain an polybenzimidazole-based aerogel material.

Abstract: Drugs in the form of very fine highly porous aerogel particles are delivered to a patient via inhalation. The aerogel particles are either an aerogelized form of a pharmaceutical or deposited upon aerogel particles produced from a non-inorganic oxide carrier matrix material, e.g. a sugar or carbohydrate. The aerogel particles are readily dissolvable by the pulmonary surfactant present in the lungs of a mammal.

Abstract: The present disclosure relates to materials and systems to manage thermal runaway issues in battery modules. In exemplary embodiments, a battery module includes battery cells separated by spacer elements. To mitigate thermal runaway issues, spacer elements may be extended to the interior surface of the enclosure. A seal is formed between the spacer elements and the interior wall to form a thermal barrier between adjacent battery cells.

Abstract: Techniques are disclosed for electrochemical synthesis of rechargeable battery cathode precursor materials using a porous carbon element. The porous carbon element acts as an air cathode to reduce oxygen. Reduced oxygen species may oxidize a transition metal anode, thereby facilitating a room temperature redox reaction with transition metals, including those that are generally resistant to corrosion, such as nickel. The transition metal reaction product(s) may be further processed into rechargeable battery cathode materials without also synthesizing hazardous waste products.
