Abstract:
A cathode for a lithium-sulfur battery includes a sulfur-based composite layer having a porosity in a range of 60% to 99%; and a conductive polymer disposed atop the composite layer and within pores of the composite layer. Moreover, a method of forming a cathode for a lithium-sulfur battery includes providing a substrate; disposing a sulfur-based slurry layer on the substrate; freeze-drying the slurry layer to form a sulfur-based composite layer having a porosity in a range of 60% to 99%; and disposing a conductive polymer atop the composite layer and within pores of the composite layer.
