    An electrolytic cell comprising a negative electrode having as the active material a light metal and a positive electrode as the main active material a poly-dicarbon monofluoride represented by the formula (C2F)n has been found to exhibit a high discharge voltage as compared with the conventional electrolytic cell of the type using as the active material of the positive electrode a polycarbon monofluoride represented by the formula (CF)n and also been found to be excellent in flatness of discharge voltage and shelf-life. The electrolytic cell of the present invention can be produced at low cost due to high yield of (C2F)n in production, and is useful as the energy source of such devices as watch, clock, desk type computer, small type radio, etc.

    This invention relates to chemical current sources and relates to a positive electrode based on carbon fluoride.
    Current sources are known, which contain a negative light metal electrode, an electrolyte and a positive carbon fluoride-based electrode containing a formula (CFx), where O X 0.25 1 and 0.9 X 1.3 2,
    However, the degradation temperature of such: polycarbon-fluoride compounds is close to the temperature of their synthesis, and the electrical characteristics, especially the discharge voltage, are not high enough.
    The purpose of the invention is to increase the electrical characteristics.
    For this, in the proposed current source, polyficarbon monofluoride is taken as carbon fluoride with the general formula 50100 mol.% in the positive electrode.
    Although the polycarbon monofluoride compound theoretical content
    fluorine is less than in a conventional polycarbon-single-fluoride compound, but when used as an active substance in a current source, it gives a high electromotive force and good current-voltage characteristics, for example, in terms of uniformity of discharge voltage, high energy density and no leakage.
    ten
    The specific gravity of the compound () n is about 2.8, while the specific gravity (CF) is about 2/7. Polydicarbon-single-fluoride compound (CrjF) receive
    15 by the reaction of microparticles of carbon material having a Franklin index of approximately from O to 0.6 with fluorine at a temperature of 3OO-ZOO C up to those Tjop, until it reaches
    20 complete fluorination of carbonaceous material consisting of microparticles.
    The product yield is 100%. Decomposition of this product does not occur at all.
    FIG. 1-7 are given characteristics
    25 proposed current source.
    Example. Powder of polydicarbon-single-fluoride compound (C (F) obtained by the reaction of natural graphite with fluorine, at a temperature of 375 C, 30 under a pressure of fluorine of 760 mm Hg).
    For 120 hours, mixed with an electrically conductive agent, such as
    powdered coal, acetylene black, or a similar material, and a binder, such as a porous polyethylene or fluoropolymer, such as polytetrafluoroethylene, or expanded graphite, to prepare a mixture of the active substance. for a positive electrode. This can be easily molded to form a positive electrode. Carbon black, or acetylene black, as an electrically conductive agent, can be used in an amount of 3-20 wt.%, Preferably 3-15 wt.%. The binder may be used in an amount of 1-10% by weight. The higher the content (CrH) l in the mixture of active material, the better the electrochemical characteristics of the positive electrode
     Since polydicarbon monofluoride compound (C, P) y is more electrically conductive than polydicarbon monofluoride compound (CF) vi, the amount of electrically conductive agent included in this mixture may be less in the case of use ( use case (CF).
    A positive electrode is obtained simply by forming a mixture, preferably around a metal collector.
    The negative electrode is a light alkali metal or alkaline earth metal.
    The electrolyte used in the proposed current source is generally non-aqueous.
    The positive electrode from the compound (C, P) "gave a small overvoltage, compared with the positive electrode from the compound (CP)".
    The discharge voltage is 3 V from 2.8 V for the electrode {CF) ".
