  Structure of the residual carbon made by fluorocarbon pyrolysis

  摘要：

  Fluorocarbon defluorination products show an unusual temperature dependence for the paramagnetic susceptibility in the range 77-300 K after pyrolysis at 650-1000-degrees-C, which is explained from dynamic equilibrium between the formation and dissociation of free radicals involving a bond energy of 11.22 kJ/mole. The ESR line width initially increases with temperature but then decreases. The width of the inhomogeneously broadened line has been calculated as a function of the frequencies of the static and dynamic spin exchange, which shows that at low temperatures there is a local increase in the radical concentration, but at higher temperatures, the dynamic exchange averages out this dipole spin-spin interaction. A suggestion confirmed by x-ray structure analysis is that the products contain a linear form of carbon.

  of the relation between the cathode overpotentials and structures of two kinds of graphite fluorides, (CF)/SUB n/ and (C/sub 2/F)/SUB n/ in nonaqueous lithium battery. The overpotential of (CF)/SUB n/ electrode decreased with increasing interlayer spacing and decreasing thickness of the crystallite along the C axis. However, it was found that the overpotential of (C/sub 2/F)/SUB n/ electrode primarily

  Electrochemical characteristics of fluorine intercalated graphite fiber-lithium cells have been investigated in 1 M LiClO4-propylene carbonate solution. Fluorine intercalated fibers were prepared by the direct reaction of elemental fluorine with graphite fibers derived from a benzene precursor material at various temperatures ranged from 345 to 614°C. The OCV decreased from 3.48 V with increasing the
