    摘要: A lithium salt-graphene-containing composite material and its preparation method are provided. The composite material has the microstructure which comprises carbon nanoparticles, lithium salt nanocrystals and graphene, wherein the surface of lithium salt nanocrystals is coated with carbon nanoparticles and graphene. The preparation method comprises concentrating and drying a mixed solution, then calcinating the solid.

For the more uniform and compacted combination between graphene and lithium salt nanocrystals, the graphene will not fall off and the composite material has a high capacity ratio, energy density and conductivity. Furthermore, particle agglomeration and growing up are reduced in the process of calcination.

    摘要: A Pt/graphene catalyst comprises graphene as carrier, and Pt loaded on the graphene. The use of graphene as carrier for the catalyst takes advantage of the ion effect and two-dimensional ductility of graphene, which increases the stability of the catalyst. The catalyst is prepared by a reverse micelles system method which provides a micro-environment (i.e. water-in-oil microemulsion), so that the particle size of the resulting nano-particles can be regulated easily and is more uniformly distributed. The use of the catalyst in electrochemostry is also disclosed.
