ELECROCHEMICAL INTERCALATION OF SODIUM INTO FULLERITE C_(60) USING SOLID ELECTROLYTES

摘要

The intercalation of sodium ions from a solid electrolyte into fullerite C_(60) was carried out in a three-electrode cell. The X-ray diffraction analysis of the intercalate indicated that a new phase was formed; its composition was calculated to be Na_(1.1)C_(60). Voltammograms of intercalation-deintercalation process and symmetrical Pt/Na_(1.1)C_(60)/Pt cells, a total resistance of symmetrical cells at a.c., the impedance hodographs at different temperatures evidenced that the intercalate has a mixed conductivity with similar contributions of electronic and ionic components.
