Abstract

A lithium-sulfur battery is provided. More specifically, a lithium-sulfur battery including a polymer non-woven fabric containing a liquid electrolyte between a positive electrode including sulfur and a separator is provided. By including a polymer non-woven fabric containing a liquid electrolyte between a positive electrode and a separator, the lithium-sulfur battery according to the present invention is capable of continuously supplying the liquid electrolyte to the positive electrode, and suppressing polysulfide elution. Accordingly, the lithium-sulfur battery has a reduced discharge overvoltage, and exhibits excellent discharge capacity and life time properties.
