Fibrous carbon materials have a variety of dimensions and structures. However, these materials were earlier restricted for use as anode materials for lithium ion batteries due to their cost and performance. With the development of nanotechnology, some modified and new forms of carbon fibers have emerged, which show good performance as anode materials. This paper reviews recent domestic and foreign...
Graphene oxide was synthesized from expanded graphite powder by a simple one-step oxidation method. A CuO/graphene composite was then obtained using a hydrothermal method. The samples were characterized using AFM, XRD, SEM, TEM and electrochemical measurements. Results show that CuO acts as a spacer to prevent the agglomeration of graphene sheets. The graphene formed a 3D conducting network for fast...
A criterion for the intercalation of a metal chloride in a molten state into graphite was proposed based on the thermodynamics of the intercalation reaction and chemical band theory. The valence electronegativity of element and ionic potential are taken as the chemical band parameters and a band parameter function γ is defined as a criterion to select a guest metal chloride to prepare a graphite intercalation...
Natural microcrystalline graphite with high sphericity and narrow size distribution was prepared by powder engineering methods. The shape of microcrystalline graphite (MCG) particles was modified using a wet agitating method and then the particles were separated into groups with narrow size distribution by means of gravity settling and hydrocyclone combined. Several methods such as scanning electron...
