ELECTROCHEMICAL REDUCTION OF GRAPHITE AND FULLERENES FROM SOLID LITHIUM SALT POLYMER ELECTROLYTES

Electrochemical reduction of graphite and fullerenes has been carried out in solid state cells operating with solid polymer electrolytes bas ed on poly(ethyleneoxide), (PEG), complexed with lithium perchlorate. Low speed cyclic voltammetry, galvanostatic reduction and oxidation ex periments give evidence for different successive redox states which ap pear during the cycling of both carbon materials. Preliminary electron diffraction studies have been performed on selected intercalated full erenes.
