The present invention relates to an anode containing a solid super acid and a lithium-sulfur secondary battery comprising the same. The present invention is intended to enhance electrochemical characteristics and lifetime characteristics of the anode using sulfur as an active material. The anode for the lithium-sulfur secondary battery according to the present invention contains sulfur and a solid super acid. Since the solid super acid in the anode does not affect the electrochemical characteristics of the anode containing sulfur, sulfur itself can be utilized as the anode active material without any technical processing. Accordingly, the energy density reduction of the lithium-sulfur secondary battery can be minimized. The solid super acid in the anode can enhance the long-term lifetime specificity of the lithium-sulfur secondary battery by controlling the polysulfide, which is an intermediate product of a charge and discharge reaction of lithium and sulfur.
