Abstract
A lithium-sulfur cell includes a lithium-containing anode, a sulfur-containing cathode and a separator arranged between the lithium-containing anode and the sulfur-containing cathode. To suppress a shuttle mechanism and to prevent a loss of active material, the separator includes a base layer and a polysulfide barrier layer. The polysulfide barrier layer is formed on the cathode side of the separator.
