Localizaed N2 adsorption on graphites, graphite oxides and exfoliated graphites
Materials Chemistry and Physics, 1989Abstract Two graphites were used to prepare the corresponding graphite oxides by the Staudenrnaier method. Exfoliated graphites were prepared by heating these graphite oxides in vacuum up to 368K and 448K. Samples were characterized by chemical analysis, X-ray diffraction and nitrogen adsorption at 77K and 90K. Following the method proposed by Pierce,

Intercalation chemistry of graphite: alkali metal ions and beyond.
Chemical Society Reviews, 2019Reversibly intercalating ions into host materials for electrochemical energy storage is the essence of the working principle of rocking-chair type batteries. The most relevant example is the graphite anode for rechargeable Li-ion batteries which has been

Graphite Anode for Potassium Ion Battery with Unprecedented Performance.
Angewandte Chemie, 2019Graphite anode as anode for potassium ion battery (PIBs) possesses the merits of low cost and potentially high energy density, while suffers from limited cycle time and inferior stability. Here we, using concentrated electrolyte design, demonstrated that

Dynamical study of graphite and graphite intercalation compounds
Physical Review B, 1994We propose a very simple model of lattice dynamics of graphite and its intercalation compounds (GIC's): our model only uses five force constants for graphite, and seven for the GIC. It is used to calculate the dynamical matrix of the structure, and to obtain by matrix diagonalization the phonon vibration frequencies for each element of the first ...

A graphite foam reinforced by graphite particles
Carbon, 2007Graphite foam was obtained after carbonization and graphitization of a pitch foam formed by the pyrolysis of coal tar based mesophase pitch mixed with graphite particles in a high pressure and temperature chamber. The graphite foam possessed high mechanical strength and exceptional thermal conductivity after adding the graphite particles.

From Organic Matter to Graphite: Graphitization
Elements, 2014Organic compounds, which on Earth originate mainly through biological activity, are transformed under the physical conditions of Earth's crust, with the end product being graphite. In this graphitization process, they pass progressively and irreversibly through a wide variety of intermediate macrostructures and nanostructures before finally attaining ...
