A lithium-sulfur battery comprising a separator in which an adsorption layer including a radical compound having a nitroxyl radical site is formed, and in particular, to a lithium-sulfur battery suppressing elution of lithium polysulfide by using an adsorption layer including a radical compound having a nitroxyl radical site and optionally a conductive material on at least one surface of a separator. In the lithium-sulfur battery, elution and diffusion may be prevented by a radical compound having a nitroxyl radical site, a stable radical compound, adsorbing lithium polysulfide eluted from positive electrode, and in addition thereto, electrical conductivity is further provided to provide a reaction site of a positive electrode active material, and as a result, battery capacity and lifetime properties are enhanced.

Lithium-sulfur battery

An electrolyte for a lithium metal battery and a lithium metal battery including the same, more specifically an electrolyte for a lithium metal battery including a lithium salt, an organic solvent and an additive, wherein the additive includes a functional group that binds to lithium metal at one end thereof and a fluorinated hydrocarbon group at the other end. The electrolyte for the lithium metal battery includes an additive including particular functional groups to improve the stability of the lithium metal and suppress the side reaction at the surface, thereby enabling the lithium metal battery to have high capacity, high stability, and long life.

Electrolyte for lithium metal battery and lithium metal battery comprising same

The present application relates to a separator and a battery comprising the same. A separator according to an exemplary embodiment of the present application includes: a porous substrate; and a first bonding layer pattern provided on at least one surface of the porous substrate, in which each pattern constituting the first bonding layer pattern is a pattern including a second bonding layer pattern having an aperture ratio of 5% or more and 40% or less.
