Abstract
A lithium-sulfur secondary battery is disclosed, and in particular, a lithium-sulfur secondary battery in which a positive electrode includes a sulfur-carbon composite including a microporous carbon material and sulfur, or a conductive additive including a carbon material having high specific surface area. By specifying conditions of the positive electrode and an electrolyte liquid, energy density may be enhanced compared to existing lithium-sulfur secondary batteries.
