In the present work, we used two different electrochemical (EC) techniques, namely, cyclic voltammetry and normal pulsed voltammetry, applied to a highly oriented pyrolytic graphite (HOPG) electrode for anion intercalation in two different aqueous electrolytes (i.e., perchloric and sulphuric acid). We performed comparative X-ray photoemission (XPS) and Raman …

C is rhombohedral graphite-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two C sheets oriented in the (0, 0, 1) direction. C is bonded in a trigonal planar geometry to three equivalent C atoms. All C–C bond lengths are 1.42 Å.

Cu 2 Se is a high ZT material consisting of cheap and earth abundant elements. Its high thermoelectric performance is mainly based on very low thermal conductivity associated with mobile atoms. This comes with the drawback of a critical voltage, over which the material decomposes to elemental copper and a copper-deficient Cu 2−x Se phase. Composites of …

Graphite is a form of pure carbon that normally occurs as black crystal flakes and masses. It has important properties, such as chemical inertness, thermal stability, high electrical conductivity, and lubricity (slipperiness) that make it suitable for many industrial applications, including electronics, lubricants, metallurgy, and steelmaking.

Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is transformed to graphite above 1500°C (2732°F), Figure 1-4. The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.

Graphite has not been produced in the U.S. since the 1950s. Graphite occurs in the U.S. as disseminated flake graphite deposits and as graphite veins. Globally, most currently mined flake graphite deposits contain at least 8 to 12 percent graphitic carbon in deposits larger than 0.5 million metric tons (Robinson and others, 2017).
