Anode carbon graphite crystallites

This ideal carbon should also be as pure as is practical, and have the required electrical conductivity and mechanical strength to function as plant anode material. Anode carbon consists of three elements (1) graphite crystallites in various sizes, shapes, and... 

A more defective form of sp carbon fibers, carbon nanotubules (CNTbs), grown by pyrolytic deposition of carbon into anodized aluminum oxide (AAO) nanochannels, are also used as nanoelectrode arrays for electrochemical sensors. Small graphitic crystallites are deposited on the inner surface of the nanochannels. Since the crystallites do not extend very long (less than micrometers) and are structurally discontinued, the resistance is orders of magnitude higher than CNFs... 

Two types of carbon can be used as active anode materials [94, 95] soft carbon, also called graphitized carbon where crystallites are oriented almost in the same direction, and hard carbon where crystallites have disordered orientations. Both are used in lithium-ion batteries, but they do not have the same properties. 

X-Ray Diffraction Data. The QI components found in the products of hydrocarbon pyrolysis are generally brittle, infusible solids. Because of this appearance the QI are usually classified under the general heading of coke. However, to more clearly define the nature of the QI produced in this work, x-ray diffraction patterns were obtained. The crystallite parameters for a graphitic matrix, as defined in Table II, were calculated for the QI and are compared in Table II with the same parameters determined for a sample of /3-resins and for a sample of coke obtained from a test carbon anode. The x-ray diffraction pattern for the sample of /3-resins was not well defined, so the value of Lc could not be determined reliably. The values of the other /3-resin parameters are...
