摘要： (Problem)In conventional method for producing artificial graphite, in order to obtain a product having excellent crystallinity, it was necessary to mold a filler and a binder and then repeat impregnation, carbonization and graphitization, and since carbonization and graphitization proceeded by a solid phase reaction, a period of time of as long as 2 to 3 months was required for the production and cost was high and further, a large size structure in the shape of column and cylinder could not be produced. In addition, nanocarbon materials such as carbon nanotube, carbon nanofiber and carbon nanohorn could not be produced.(Means to Solve)A properly pre-baked filler is sealed in a graphite vessel and is subsequently subjected to hot isostatic pressing (HIP) treatment, thereby allowing gases such as hydrocarbon and hydrogen to be generated from the filler and precipitating vapor-phase-grown graphite around and inside the filler using the generated gases as a source material, and thereby, an integrated structure of carbide of the filler and the vapor-phase-grown graphite is produced. In addition, nanocarbon materials are produced selectively and efficiently by adding a catalyst or adjusting the HIP treating temperature.

摘要： Embodiments of the present disclosure are directed to carbon-containing composites which are suitable for use as electrodes in electrochemical systems. The composites are formed from a scaffold of graphene and carbon nanotubes. Graphene flakes form a plurality of generally planar sheets (e.g., extending in an x-y plane) separated in the direction of a composite axis (e.g., along a z-axis) and approximately parallel to one another. The carbon nanotubes extend between the graphene sheets and at least a portion of the carbon nanotubes are aligned in approximately the same direction, at a defined angle with respect to the composite axis. At least a portion of the scaffold is embedded within a porous carbon matrix (e.g., an activated carbon, a polymer derived graphitic carbon, etc.).

摘要： The present disclosure provides a method for manufacturing an energy-storage composite material. The method includes (a) providing a solution having a carbon substrate, and placing the solution in a pressure container, and a surface of the carbon substrate having an energy-storage active precursor; (b) stirring the solution having the carbon substrate at a first stirring speed, and venting air in the pressure container at a first temperature, such that a pressure in the pressure container reaches a first pressure and is maintained for a first period of time; and (c) introducing a fluid into the pressure container, stirring the solution having the carbon substrate at a second stirring speed, increasing a pressure and a temperature in the pressure container to a second pressure and a second temperature and maintaining for a second period of time, and then reducing the pressure to the atmosphere pressure to obtain an energy-storage composite material.

摘要： An asymmetric supercapacitor includes a negative electrode made of a first carbon, a positive electrode made of a soft carbon, a separator and an electrolyte. The separator is disposed in between the negative and positive electrodes. The soft carbon has an activation threshold (AT) larger than 1400, and the activation threshold (AT) is obtained from the following formula: AT=La*(Aa/Ac). La is an in-plane correlation length of the soft carbon, Aa is an area of amorphous peak of the soft carbon analysed by X-ray diffraction in Gaussian distribution graph, and Ac is an area of crystalline peak of the soft carbon analysed by X-ray diffraction in Gaussian distribution graph.

摘要： Ultracapacitor electrodes having an enhanced electrolyte-accessible surface area are provided. Such electrodes can include a porous substrate having a solution side and a collector side, the collector side operable to couple to a current collector and the solution side positioned to interact with an electrolytic solution when in use. The electrode can also include a conductive coating formed on the solution side of the porous substrate. The coating can have a first side positioned to interact with an electrolytic solution when in use and a second side opposite the first side. The coating can have discontinuous regions that allow access of an electrolyte solution to the second side during use to enhance electrolyte-accessible surface area of the conductive coating.
