ABSTRACT:
There is disclosed a method for producing a graphite fluoride for use in an electrochemical cell of the type having as the negative electrode a light metal, such as an alkali metal, an electrolyte in which the negative electrode is not dissolved, and a positive electrode which has, as an active material, a graphite fluoride produced by fluorinating a decomposition residual carbon which has been obtained by decomposing a covalent intercalation compound. The electrochemical cell of the present invention exhibits high discharge potential and low overvoltage, and excellent discharge characteristics with respect to the flatness of discharge voltage, discharge capacity and shelf-life.
