  • Publication number: 20130069011
    Abstract: In an exemplary method, a nano-architectured carbon structure is fabricated by forming a unit (e.g., a film) of a liquid carbon-containing starting material and at least one dopant. A surface of the unit is nano-molded using a durable mold that is pre-formed with a pattern of nano-concavities corresponding to a desired pattern of nano-features to be formed by the mold on the surface of the unit. After nano-molding the surface of the unit, the first unit is stabilized to render the unit and its formed nano-structures capable of surviving downstream steps. The mold is removed from the first surface to form a nano-molded surface of a carbonization precursor. The precursor is carbonized in an inert-gas atmosphere at a suitable high temperature to form a corresponding nano-architectured carbon structure. A principal use of the nano-architectured carbon structure is a carbon electrode used in, e.g., Li-ion batteries, supercapacitors, and battery-supercapacitor hybrid devices.

  • Publication number: 20130071313
    Abstract: Solvents for macromolecules generally believed to be insoluble in their pristine form are identified by generation of a “solvent resonance” in the relationship between solvent quality (deduced by Rayleigh scattering) and an intrinsic property of solvents. A local extreme of the solvent resonance identifies the ideal intrinsic property of an ideal solvent which may then be used to select a particular solvent or solvent combination. A solvent for graphene is used in the production of transparent conductive electrodes.

In one aspect, this can be accomplished by controlling the degree of rafting in a nanotube fabric. In one aspect, the method includes adjusting the concentration of individual nanotube elements dispersed in a nanotube application solution. A high concentration of individual nanotube elements will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a lower concentration will tend to discourage rafting. In another aspect, the method includes adjusting the concentration of ionic particles dispersed in a nanotube application solution. A low concentration of ionic particles will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a higher concentration will tend to discourage rafting. In other aspects, both concentration parameters are adjusted.

  • Publication number: 20120328953
    Abstract: Graphene which is permeable to lithium ions and can be used for electric appliances is provided. A carbocyclic ring including nine or more ring members is provided in graphene. The maximum potential energy of the carbocyclic ring including nine or more ring members to a lithium ion is substantially 0 eV. Therefore, the carbocyclic ring including nine or more ring members can function as a hole through which lithium ions pass. When a surface of an electrode or an active material is coated with such graphene, reaction of the electrode or the active material with an electrolyte can be suppressed without interference with the movement of lithium ions.
