Abstract

A ZnCl.sub.2 -graphite intercalation compound is synthesised by an electrochemical process in an aqueous solution. Flexible graphite is manufactured by exfoliating and then compressing the ZnCl.sub.2 -graphite intercalation compound into a sheet form. This processing is suitable for mass production. As no sulphuric acid is used in this method, the method reduces environmental pollution and corrosion during use.
