In one embodiment of the present invention, by placing the separator in the shape of graphite felt between the anode and the separator, lithium polysulfide generated during charging and discharging is physically and chemically adsorbed on the separator, thereby preventing lithium phenomenon. A sulfur cell is provided. Lithium-sulfur battery having a graphite felt by electrospinning according to an embodiment of the present invention, a positive electrode comprising a sulfur compound; A negative electrode composed of lithium; A separator positioned between the anode and the cathode; An anode and a separator, a separator formed of carbon fiber by electrospinning, having a graphite structure by carbonization, and adsorbing lithium polysulfide (Li 2 S n , 2<n≤8); And an electrolyte impregnated in the positive electrode, the negative electrode, the separator, and the separator. |
