  • Graphite material
    Patent number: 9666854
    Abstract: A graphite powder may include highly oriented grain aggregates, wherein the electrical resistivity of the powder decreases with increasing density. A process for coating a substrate may include providing a coating dispersion including such a graphite powder and applying the coating dispersion to the substrate. An electrode may contain such a graphite powder. A coating dispersion may include such a graphite powder dispersed in a liquid medium. A battery may include such a graphite powder. A compressed body of pure graphite may include such a graphite powder. A lubricant may include such as graphite powder.
