摘要： A method of forming a graphene-based material includes: (1) treating a mixture including an etchant and graphene oxide sheets to yield formation of holey graphene oxide sheets; (2) dispersing the holey graphene oxide sheets in a re-dispersal solvent to yield a holey graphene oxide dispersion including the holey graphene oxide sheets; and (3) treating the holey graphene oxide dispersion under reducing conditions to yield self-assembly of the holey graphene oxide sheets into a graphene-based material.

摘要： Methods for synthesizing macroscale 3D heteroatom-doped carbon nanotube materials (such as boron doped carbon nanotube materials) and compositions thereof. Macroscopic quantities of three-dimensionally networked heteroatom-doped carbon nanotube materials are directly grown using an aerosol-assisted chemical vapor deposition method. The porous heteroatom-doped carbon nanotube material is created by doping of heteroatoms (such as boron) in the nanotube lattice during growth, which influences the creation of elbow joints and branching of nanotubes leading to the three dimensional super-structure. The super-hydrophobic heteroatom-doped carbon nanotube sponge is strongly oleophilic and can soak up large quantities of organic solvents and oil. The trapped oil can be burnt off and the heteroatom-doped carbon nanotube material can be used repeatedly as an oil removal scaffold. Optionally, the heteroatom-doped carbon nanotubes in the heteroatom-doped carbon nanotube materials can be welded to form one or more macroscale 3D carbon nanotubes.

摘要： Mixture of particles comprising a non-conducting or semi-conducting nucleus covered with a hybrid conductor coating and hybrid conductor chains located between the particles of the mixture to constitute a conductivity network, that is prepared by mechanical crushing. Due to a very good conductivity of the network, a low resistivity, a very good capacity under elevated current and/or a good density of energy, these mixtures of particles are advantageously incorporated in anodes and cathodes of electrochemical generators, resulting in highly performing electrochemical systems.

摘要： In an external member, peripheral edge regions of first and second metal foil layers are joined via a periphery sealing portion containing thermoplastic resin. A plurality of bare cells are arranged separately in internal spaces surrounded by the first metal foil layer, the second metal foil layer and the periphery sealing portion. The partition region of the first metal foil layer between adjacent bare cells and the partition region of the second metal foil layer between adjacent bare cells are joined via the partition sealing portion. Thus, the internal space is partitioned into a plurality of independent individual spaces. At each individual space, the first metal foil inner exposed portion and the positive electrode portion are connected electrically, and the negative electrode portion of the second metal foil inner exposed portion and the bare cell are connected electrically. The bare cell and electrolyte are encapsulated in each individual space.
