Abstract
Disclosed is a metal-sulfur electrode for a lithium-sulfur battery and a method for preparing the same. More particularly, a metal-sulfur electrode for a lithium-sulfur battery is prepared by coating a slurry mixture including sulfur, a conductive material and a binder as an electrode active material on a metal electrode and drying the same while applying an electric field such that the conductive material is aligned adequately so as to provide maximize efficiency during repeated charging and discharging when used in the anode of the lithium-sulfur battery.
