✦ Synopsis

Fluorine intercalated carbon fibres, (CF), , have been prepared from benzenederived, vapourgrown carbon fibres, and have a high degree of preferred orientation of the carbon layers along the fibre axis. The (CF), fibres have been obtained through direct reaction with elemental fluorine at temperatures as low as 300 "C, using carbon fibres of diameter 0.1 -1.0 pm. The fibres have been used as the cathode material in a lithium battery with 1 M LiCIOe--propylene carbonate solution. The discharge potential of (CF), fibres is about 0.5 V higher than that of conventional graphite fluoride (CF), at a load of 0.5 mA cmm2 and with a cathode utilization of -80%. It is suggested that this high performance is due to the chemical and physical characteristics of the fibrous compounds.
