  • Patent number: 6756027
    Abstract: A method of preparing graphite intercalation compounds in which graphite particles are immersed in an aqueous electrolyte media comprising both an acid and an oxidizing agent. The immersed graphite particles are subjected to an anodic current and then removed from the electrolyte and rinsed with a solvent. The excess solvent and electrolyte is then removed from the graphite particles. The graphite particles may be placed in a plating barrel which is immersed in the electrolyte and rotated while the graphite particles are subjected to the current. The resultant intercalated graphite has an expansion volume of from between about 100 ml/g to 2000 ml/g when heated to 1000° C.

  • Publication number: 20040048162
    Abstract: An engineered carbonaceous material (ECM) comprising a mixture of synthetic graphite and one or more other graphite, such as natural flake graphite, natural vein graphite, and/or amorphous graphite. The objects are also achieved by an ECM comprising a mixture of expanded graphite and one or more other graphite materials, such as natural flake graphite, natural vein graphite, amorphous graphite and/or synthetic graphite. The ECM is preferably mixed with 0.01 to 20.0 wt. % MnO2 to create a battery active material. The mixtures may be made by either co-blending or co-grinding the graphites together. An electrochemical cell incorporating the material is also contemplated.
