Keywords: Intercalate
Formic acid
Issue Date: 16-Dec-1997
Citation: US Patent 5,698,088. Washington, DC: US Patent and Trademark Office, 1997.
Abstract: A graphite intercalation compound is disclosed in which formic acid (HCOOH) is the intercalate. The GIC may be formed by an electrochemical process using formic acid solution as both the electrolyte and as the intercalate source.The resulting formic acid GIC may be expanded by rapid heating to produce an expanded graphite product that in turn may be mechanically processed into flexible graphite.
