Abstract
Abstract 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.
