A process for fabricating a carbon composite structure that is lightweight, structurally sound, and characterized by high heat capacity. A carbon structure is devised with cavities therein receiving a phase change medium. The phase change medium demonstrates both high energy absorption capacity and high thermal conductivity and is formed from a carbon fiber to establish a high porosity medium having a large volume fraction. The surface energy of the carbon fibers is enhanced in various ways as by deposition of a carbide former, a metallurgical coating or a precursor liquid or by electroplating or etching the surfaces of the carbon fibers. The enhanced surface energy allows for the retention of phase change material.

An electrode material for a secondary battery has a carbon fiber. This carbon fiber has a coaxial stacking morphology of truncated conical tubular graphene layers, wherein each of the truncated conical tubular graphene layers includes a hexagonal carbon layer, and has a large ring end at one end and a small ring end at the other end in an axial direction. The hexagonal carbon layers are exposed on at least a part of the large ring ends. Such an electrode material for a secondary battery excels in lifetime performance, has a large electric energy density, enables an increase in capacity, and excels in conductivity and electrode reinforcement.

Methods of making a cathode element for an electrochemical cell. The methods comprise providing hollow carbon nanotubes and a sulfur source in a closed environment. Sulfur is deposited within an interior of the hollow carbon nanotube. The method includes cleaning an exterior surface of the carbon nanotubes and incorporating the carbon nanotubes into a cathode element. A cathodic material for a lithium-sulfur electrochemical cell is also provided. The material comprises a plurality of stacked-cone carbon nanotubes. Each nanotube defines a hollow interior and has a substantially continuous exterior surface area. Elemental sulfur is disposed within the hollow interior of each nanotube.

A method of depositing silicon on carbon nanomaterials such as vapor grown carbon nanofibers, nanomats, or nanofiber powder is provided. The method includes flowing a silicon-containing precursor gas in contact with the carbon nanomaterial such that silicon is deposited on the exterior surface and within the hollow core of the carbon nanomaterials. A protective carbon coating may be deposited on the silicon-coated nanomaterials. The resulting nanocomposite materials may be used as anodes in lithium ion batteries.

A method for producing a diamond/carbon/carbon composite is provided which includes the steps of densifying a preform of interwoven vapor grown carbon fibers form a carbon/carbon composite, and then depositing a polycrystalline diamond film on the carbon/carbon composite. The preform may be densified by depositing pyrolyric carbon into the interstices of the preform, either by a chemical vapor infiltration process or by a pitch infiltration process. The polycrystalline diamond film is deposited on the carbon/carbon composite by a microwave plasma enhanced chemical vapor deposition process. The resulting diamond/carbon/carbon composite can be utilized as an integral dielectric heat sink by depositing metallic circuits on the diamond layer of the diamond/carbon/carbon composite.
