Abstract

A Li—S battery including a cathode and an anode and at least one of a lithium-containing liquid electrolyte, gel electrolyte, and solid electrolyte disposed between the cathode and the anode. The cathode includes at least one of an electrically conductive carbon material, an electrochemically active cathode material that comprises sulphur, and at least partially fibrillar plastic material. The anode includes a conducting substrate which is coated at least in regions with at least one of silicon and tin. A method for operation thereof.
