Ultrastable cathodes for lithium sulfur batteries

Title: Ultrastable cathodes for lithium sulfur batteries

Abstract

A cathode for a lithium-sulfur battery includes a copper-containing current collector, over which an active material layer is disposed. A method of producing the cathode is provided. A lithium-sulfur battery including the cathode provides improved capacity and cycleability.
