PURPOSE: To improve the discharge potential, specific capacity and the utilization of the cell and to reduce the cost, by employing the graphite fluoride shown by (C2F)n to be produced through the reaction between the artifitial graphite and the fluorine as the main component of the cell active substance.
CONSTITUTION: The graphite fluoride shown by (C2F)n to be produced through the reaction between the artifitial graphite and the fluorine is employed as the main component of the cell active substance. Said cell active substance is employed as the positive pole of the cell while the alkali metal such as Li, alkali earth metal such as Mg, Ca or Al or Al alloy is employed for the cathode. Water system or non-water system electrolyte can be used. The cell thus composed has high specific volume and the utilization of the active substance per unit volume and the high discharge potential, while having the excellent flatness and the good storage life. While since the artifitial graphite is used, (C2F)n can be manufactured in short time with high yield resulting in the considerable reduction of cost.
