Abstract
An lithium-sulfur battery including an anode structure, a cathode, a separator, and an electrolyte is provided. The electrolyte may be dispersed throughout the cathode and in contact with the anode. An artificial solid-electrolyte interphase (A-SEI) may form on the anode, and a protective layer (e.g., that may be pinhole free) may form within and/or on the A-SEI to face the cathode. The protective layer may be formed from carbonaceous materials, which may provide exposed carbon atoms grafted with one or more ions, such as fluorine anions (F−), uniformly dispersed throughout the protective layer. In addition, the protective layer may include polymeric chains positioned generally opposite to each other. The polymeric chains may cross-link upon exposure to ultraviolet (UV) energetic radiation to form a three-dimensional (3D) lattice having a defined cross-linking density suitable to trap one or more anions during discharge-charge operational cycling of the lithium-sulfur battery.
