The present invention relates to a paper electrode for a lithium-sulfur battery, a method for manufacturing the same, and a lithium-sulfur battery including the same, wherein the paper electrode for a lithium-sulfur battery includes a porous polymer fiber layer including polymer fibers and a porous polymer fiber layer. And a functional polymer fiber layer including a functional group having a negative surface charge, and an electrode layer including a multi-walled carbon nanotube-sulfur composite and a single-walled carbon nanotube formed on the functional polymer fiber layer. Battery paper electrode manufacturing method, using a first dispersion solution containing a polymer fiber, forming a porous polymer fiber layer, on the porous polymer fiber layer, comprising a functional polymer fiber containing a functional group having a negative surface charge Filtering the second dispersion solution under reduced pressure to form a functional polymer fiber layer, Preparing a multi-walled carbon nanotube-sulfur composite by mixing and heat treating the multi-walled carbon nanotubes and the sulfur precursor, and forming a third dispersion solution by mixing the multi-walled carbon nanotube-sulfur composite and the single-walled carbon nanotubes. And vacuum-filtering the third dispersion solution on the functional polymer fiber layer to form an electrode layer including a multi-walled carbon nanotube-sulfur composite and a single-walled carbon nanotube. |
