Discharge Characteristics of Poly(Carbon Monofluoride) Prepared from the Residual Carbon Obtained by Thermal Decomposition of Poly(Dicarbon Monofluoride) and Graphite Oxide

Abstract

The discharge performances have been investigated of poly(carbon monofluorides), , prepared from the residual carbons obtained by the thermal decomposition of poly(dicarbon monofluoride), and graphite oxide. The residual carbons were composed of such crystallites having a smaller size along c‐axis than the dimension of ab‐axis. They were easily fluorinated, giving at a relatively low temperature in a short time. prepared with the present method had higher discharge potentials than the graphite fluorides prepared by direct fluorination in a nonaqueous lithium cell. The maximum increase of energy density achieved at the current density of 0.5 mAcm−2 was about 30%. The utility of fluorine was almost 100%, and the flatness of discharge potential was also quite good.
