Abstract
Electrochemical cells for lithium-sulfur batteries include a cathode comprising a sulfur containing material, an anode comprising lithium, a separator between the anode and cathode and an interlayer extending from a perimeter of the separator in a direction perpendicular to a stacking direction. The interlayer is configured to prevent polysulfide migration from the cathode to the anode.
