CARBON FLUORIDE AND METHOD FOR ITS PRODUCTION Russian patent published in 1996 - IPC

Abstract RU 2054375 C1

FIELD: manufacture of electrodes of chemical current sources. SUBSTANCE: the invention offers carbon fluoride for electrodes of chemical current sources. Carbon fluoride contains CF and CF₂ groups in ratio of (2-4.5): 1. In this case, groups CF₂ inside planes (CF)n, where n=3000-50000 and correspond to formula CF_x, where x=1.18-1.33. Method for production of carbon fluoride includes treatment of carbon black densified with pyrolytic carbon, fluorinating agent - fluorine, or chlorine trifluoride, and inert gas taken in ratio of 1:(1-3) at temperature of 200-400 C. Carbon fluoride contains 65.5-67.8% of fluorine and possesses high specific surface (650-500 sq.m/g) and low porosity. Chemical current source with use of electrode made of carbon fluoride CF_1,33 has discharge current of 100 mcA/sq.cm with discharge voltage of 2.2-2.3 V. EFFECT: improved capacitance and discharge characteristics of chemical current sources based on carbon fluoride electrodes. 5 cl, 2 tbl
