Abstract
An anode structure of a lithium sulfur battery includes a sulfur anode laminated on an aluminum foil, and a carbon coating layer disposed between the sulfur anode and a carbon structure layer in which sulfur is immersed. The sulfur anode includes the sulfur, a conductor, and a binder. The carbon structure layer in which sulfur is immersed is a polyester (PE) separation membrane separated from a counter electrode. A loaded amount of sulfur within the anode structure is dispersed to the sulfur anode and the carbon structure layer in which the sulfur is immersed.
