摘要： A unitary graphene layer or graphene single crystal containing closely packed and chemically bonded parallel graphene planes having an inter-graphene plane spacing of 0.335 to 0.40 nm and an oxygen content of 0.01% to 10% by weight, which unitary graphene layer or graphene single crystal is obtained from heat-treating a graphene oxide gel at a temperature higher than 100° C., wherein the average mis-orientation angle between two graphene planes is less than 10 degrees, more typically less than 5 degrees. The molecules in the graphene oxide gel, upon drying and heat-treating, are chemically interconnected and integrated into a unitary graphene entity containing no discrete graphite flake or graphene platelet. This graphene monolith exhibits a combination of exceptional thermal conductivity, electrical conductivity, mechanical strength, surface smoothness, surface hardness, and scratch resistance unmatched by any thin-film material of comparable thickness range.

摘要： The invention provides a method of producing a graphene material from a starting graphitic material. In an embodiment, the method comprises: (a) dispersing the starting graphitic material in a liquid medium to form a graphite suspension; and (b) introducing the graphite suspension into a hydrodynamic cavitation reactor that generates and collapses cavitation or bubbles in the liquid medium to exfoliate and separate graphene planes from the starting graphitic material for producing the graphene material. The process is fast (minutes as opposed to hours or days of conventional processes), environmentally benign, and highly scalable. The reactor can concurrently perform the functions of graphene production, chemical functionalization, dispersion, and mixing with a polymer to make a composite.

摘要： A lithium secondary battery comprising a positive electrode, a negative electrode comprising a carbonaceous material which is capable of absorbing and desorbing lithium ions, and a non-aqueous electrolyte disposed between the negative electrode and the positive electrode. The carbonaceous material comprises a graphite crystal structure having an interplanar spacing d002 of at least 0.400 nm (preferably at least 0.55 nm) as determined from a (002) reflection peak in powder X-ray diffraction. This larger interplanar spacing implies a larger interstitial space between two graphene planes to accommodate a greater amount of lithium. The battery exhibits an exceptional specific capacity, excellent reversible capacity, and long cycle life.
