An electric cell comprising a negative electrode having a light metal as an active material, an electrolyte and a positive electrode having, as an active material, a fluorinated graphite having the formula (CxF)n wherein x is a numerical value of about 2.0 to about 5.5 and n refers to an indefinite number of the recurring (CxF) unit and having a crystalline structure exhibiting a peak at about 13.7 DEG to about 15.0 DEG in terms of an angle of 2 theta corresponding to the diffraction at the (001) plane in an X-ray diffraction pattern, a peak in the vicinity of 685.3 eV due to the F1S and two peaks in the vicinity of 287.5 eV and 284.3 eV due to the C1S in the spectrum of electron spectroscopy of chemical analysis, two peaks in the vicinity of 1100 cm-1 and 1240-1 in the IR spectrum, an electric conductivity of at least about 10-8 OMEGA -1cm -1 and a thermal stability up to 200 DEG C. in air from the viewpoint of an X-ray diffraction pattern. The electric cell is advantageously used in devices requiring a high voltage such as a watch, a clock, a small radio, a small computer, etc.
