FIG U RE 12.2 Typical voltage profiles from carbon materials with different heat-treatment temperatures and different structural variations. The profiles were obtained at the second cycle, and (a) and (b) show discharge and charge cycles by using graphitizable carbon heat-treated at 3000°C, graphitizable carbon heat-treated at 2000°C, and nongraphitic carbon obtained at 700°C.

Although the great majority of petroleum and coal-based pitch materials, as well as model compounds such as polyvinyl chloride, acenaphthylene, decacyclene and polynuclear aromatic hydrocarbons, form anisotropic graphitizable carbons, it is an almost impossible task to predict the type of optical texture of a coke from an elemental analysis of the pitch. The size, shape and reactivity of peri-condensed polynuclear aromatic molecules in the products of pyrolysis of a pitch play a more important role in determining optical texture. [Pg.19]

Graphite Intercalation Compounds.— The reactions of graphitizable carbons leading to the formation of graphite intercalation compounds have been reviewed. Emphasis was placed on the insertion of alkali metals (Na), halogens (Brg), and acids (H2SO4). The effects of electronic structure and electron exchange on intercalation reactions were also considered. [Pg.238]

While borazine is analogous in shape and structure to benzene, the behavior observed here differs sharply from that of benzene. During the pyrolysis of benzene at temperatures in excess of 500 C, linear biphenyl, terphenyl and polyphenyl units are formed which do not exhibit liquid crystallinity [22]. In contrast, when naphthalene or anthracene are heated, they will enter a liquid crystalline mesophase and will produce graphitizable carbon upon continued pyrolysis (Figure 2.3). This mesophase consists of a wide range of planar, polynuclear species which have a tendency to stack, thereby forming a discotic phase. The mesophase is also observed to form when a 50 50 mixture of benzene and naphthalene is heated [23]. [Pg.44]
