Carbon material for negative electrode of secondary lithium battery,

Disclosed is a novel fluorocarbon comprising carbon atoms and fluorine atoms and having no double bond, the atomic ratio of fluorine to carbon atoms being 1.50 to 1.93, which exhibits a liquid state at room temperature. The liquid fluorocarbon has excellent water- and oil-repellent properties and can advantageously be used, for example, not only as a water- and oil-repellent but also as an inert liquid, a heat transfer agent and a vapor phase soldering liquid in various fields, especially in the electronic industry. The liquid fluorocarbon can be obtained directly from a pitch or from a pitch fluoride which can be obtained by direct fluorination of a pitch.
