Abstract: The present invention relates to a positive electrode of a lithium-sulfur secondary battery containing a sulfur-infiltrated porous conductive nanocomposite, and more specifically, to a positive electrode of a lithium-sulfur secondary battery containing a sulfur-infiltrated porous conductive nanocomposite, which produces the sulfur-infiltrated porous conductive nanocomposite by filling sulfur particles inside pores of a porous conductive material, coating a surface of the porous conductive material with oxidized silicon, after which an empty space inside the pores is secured by partially evaporating sulfur through heat processing. Thus, lithium polysulfide is confined to be kept from diffusing to the outside, precluding an occurrence of a polysulfide shuttle phenomenon, which prevents a self-discharging effect during charging, thereby inducing an effect of extending a lifetime of the battery.
