A lithium-sulfur battery may include a cathode, an anode structure positioned opposite to the cathode, a separator, and an electrolyte. In some instances, the anode structure may include an artificial solid-electrolyte interphase (A-SEI) that may form on and within the anode structure. A protective layer may form within and on the A-SEI, and may include exposed carbon surfaces formed by coalescence of several wrinkled graphene nanoplatelets with one another. Metal-containing substances may be decorated on and/or attached with at least some exposed carbon surfaces and regulate flow of lithium (Li) cations within the lithium-sulfur battery and correspondingly moderate one or more of a plating rate or a de-plating rate of lithium onto the anode structure. The separator may be positioned between the anode structure and the cathode. The electrolyte may be dispersed throughout the cathode and in contact with the anode structure.

A lithium-sulfur battery including an anode, a cathode, a separator, and an electrolyte is provided. The lithium-sulfur battery may be formed as a jelly roll. The anode may output lithium cations (Li) and a solid-electrolyte interphase (SEI) may be formed on the anode. A protective layer may be formed at least partially within and on the SEI. In addition, the protective layer may be positioned proximal to the anode and include wrinkled graphene nanoplatelets and fluorinated poly(meth)acrylates. For example, multiple wrinkled graphene nanoplatelets may be adjoined to one another by flexure points, where each flexure point may provide exposed carbon atoms. In this way, the fluorinated poly(meth)acrylates may be grafted onto at least some exposed carbon atoms. At least some fluorinated poly(meth)acrylates may be compatible with polymerization and cross-linking with one another responsive to exposure to one or more of free-radical initiators or an ultraviolet (UV) energetic environment.

A method of manufacturing a lithium-sulfur battery in a cylindrical cell format is provided. In some aspects, the method includes providing an anode current collector and providing an anode on the anode current collector. The method may include depositing a protective layer on and along the length of the anode, providing a cathode current collector opposite to the anode, and providing a cathode on the cathode current collector. The method may include providing a separator between the anode and the cathode, disposing an adhesive carbon-containing layer along the bottom edge of the anode (e.g., to replace one or more conventional anode tabs), and dispersing an electrolyte throughout the lithium-sulfur battery. The method may include forming the lithium-sulfur battery in the cylindrical cell format by collectively winding into a jelly roll.
