In one embodiment of the present invention, by placing a 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 to the separator, thereby preventing a shuttle phenomenon. Provides a sulfur battery. Lithium-sulfur battery having a graphite felt by the electrospinning according to an embodiment of the present invention, the positive electrode comprising a sulfur compound; A negative electrode comprising lithium; A separator positioned between the anode and the cathode; A separator positioned with the anode and 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. |
