Abstract
The present disclosure relates to a positive electrode active material and a positive electrode comprising metal nano particles, and a lithium-sulfur battery comprising the same, and in particular, to a positive electrode for a lithium-sulfur battery comprising a positive electrode active material of a sulfur-metal catalyst-carbon composite, and a lithium-sulfur battery comprising the same. The lithium-sulfur battery using a positive electrode comprising metal nano particles according to the present disclosure increases reactivity of sulfur, a positive electrode active material, and increases electrical conductivity of an electrode by the dispersion of the metal nano particles in the electrode so as to increase reactivity and electric capacity of the positive electrode. In addition, battery reaction products such as lithium sulfide (LiS) are readily decomposed by a catalyst reaction, and therefore, lifespan characteristics can be improved.
