#This application claims priority to and the benefit of International Application No. PCT/KR2013/007330, filed on Aug. 14, 2013, which published as WO2014/027841, and further claims priority to Korean Patent Application No. 10-2012-0089628, filed in the Korean Intellectual Property Office on Aug. 16, 2012, the entire disclosure of which is incorporated by reference.

#The present invention relates to a method of fabricating an anode for lithium-sulfur batteries and a lithium-sulfur battery.

#The rapid development of portable electronic devices is increasing the demand for secondary batteries. In particular, the trend toward smaller, lighter, thinner and more compact portable electronic devices is continuously requiring the introduction of high-energy density batteries as well as inexpensive, safe, and environment-friendly batteries.

#The aspects and features of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings, in which:

#FIG. 1 is a perspective view of a lithium-sulfur battery;

#FIG. 2 is a photograph of a carbon thin layer prepared in Example 1;

#According to an aspect of the present invention, there is provided a method of fabricating an anode for lithium-sulfur batteries. The method includes: mixing a carbon raw material and a binder; obtaining a carbon layer by preparing the mixture of the carbon raw material and the binder in the form of a layer; drying the carbon layer; forming a carbon thin layer by compressing the dried carbon layer; and stacking the carbon thin layer on an anode for lithium-sulfur batteries.

#The carbon raw material may be ketjen black, denka black, acetylene black, Super-p, carbon black, graphene, or any combination thereof.

#The drying of the carbon layer may be performed at 50 to 100° C.
