X-RAY CHARACTERIZATION OF CATHODE CARBON MATERIALS

An X-ray diffraction method has been developed to characterize graphitic cathode carbon materials by the intensity of the d002 peak, p002, relative to a manufactured electrographite (CS-49B, Union Carbide) as secondary standard. The carbon powder particles of the sieve fraction < 7 5 mum were spread on a plane quartz supporter using spray adhesive and sieving the sample powder regularly on the glue film to reach random particles distribution. Reproducibility and standard deviations < 3% for the standard electrographite and < 5% for graphitic carbon materials have been obtained. The method is useful for operational characterization of cathode carbon material as well as for quality control.
