Abstract: Provided herein are composite materials for use in an electrical energy storage system (e.g., a high-capacity battery) and methods for preparing the same. The composite materials provided herein are also useful as substrates for chemical vapor deposition of silicon. The composite materials of the present disclosure include a three-dimensional carbon network and optional silicon particles. The composite materials further include mega pores, at least some of which are formed by carbonizing sacrificial particles dispersed throughout a three-dimensional network. The mega pores advantageously provide a space to accommodate the strain and stress in the electrode structure due to volume changes of silicon (particles) during charge and discharge of the electrical energy storage system.

Abstract: Conglomerate particles comprising a porous carbon matrix with a plurality of cathode material particles at least partially embedded in the matrix are disclosed, as well as methods for their manufacture using predominantly aqueous chemistry. The conglomerate particles demonstrate surprisingly improved electrochemical properties when used as cathode materials as compared to the cathode material particles when non-embedded.

Abstract: The present invention provides a fiber-reinforced aerogel material which can be used as insulation. The fiber-reinforced aerogel material is highly durable, flexible, and has a thermal performance that exceeds the insulation materials currently used. The fiber-reinforced aerogel insulation material can be as thin as 1 mm or less, and can have a thickness variation as low as 2% or less. Also provided is a method for improving the performance of a battery by incorporating a reinforced aerogel material into the battery. Further provided is a casting method for producing thin fiber-reinforced aerogel materials.
