Zusammenfassung:	The present disclosure relates to an aqueous binder for a lithium-sulfur secondary battery, a method for preparing the same, and a lithium-sulfur secondary battery including the same. More particularly, it is possible to obtain an aqueous binder (PEI/PVP/CA, PPC) by adding citric acid to a mixed solution of polyethylene imine with polyvinyl pyrrolidone, and to apply the aqueous binder to a lithium-sulfur secondary battery having high discharge capacity, Coulombic efficiency and stable life characteristics through the improvement of adhesion capability even at a sulfur cathode with high energy density, inhibition of a shuttle reaction and inhibition of metal current collector corrosion.
