Abstract: A lithium-sulfur battery including an anode structure, a cathode, a separator, and an electrolyte is provided. A protective layer may form within the anode structure responsive to operational discharge-charge cycling of the lithium-sulfur battery. The protective layer may include a polymeric backbone chain formed of interconnected carbon atoms collectively defining a segmental motion of the protective layer. Additional polymeric chains may be cross-linked to one another and at least some carbon atoms of the polymeric backbone chain. Each additional polymeric chain may be formed of interconnected monomer units. A plasticizer may be dispersed throughout the protective layer without covalently bonding to the polymeric backbone chain. The plasticizer may separate adjacent monomer units of at least some additional polymeric chains. Increasing separation of adjacent monomer units increases a cooperative segmental mobility of the additional polymeric chains and ionic conductivity of the protective layer.

Abstract: A lithium-sulfur battery including an anode, a cathode, a separator, and an electrolyte dispersed throughout the lithium-sulfur battery is provided. The anode may output lithium ions. The cathode may be positioned opposite to the anode and have an overall porosity as defined by multiple non-hollow carbon spherical (NHCS) particles joined together to form tubular NHCS particle agglomerate. Pores may be associated with the overall porosity of the cathode and interspersed uniformly throughout the NHCS particles. In some aspects, each pore having a diameter between 1 nm and 10 nm; and each tubular NCHS agglomerate has a length between 5 micrometers (μm) and 35 μm. Interconnected channels defined in shape by the NHCS particles may be joined to each other and the pores, where some interconnected channels may be pre-loaded with an elemental sulfur and retain polysulfides (PS). Retention of the polysulfides may be based on some NHCS particles.

Abstract: 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.

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.

Abstract: Thick cathodes associated with cylindrical lithium-sulfur batteries. The cathodes include one or more structured layers of agglomerates of carbonaceous particles disposed on opposing sides of a cathode current collector. The structured layers on each side of the cathode current collector may be characterized by varying agglomerate size and thickness of the structured layers. The structured layers of agglomerates may improve electrochemical kinetics and sulfur utilization within thick cathodes. The structured layers of agglomerates may decrease the number of interconnection or failure points between agglomerates disposed across the thickness of the structured layers on each side of the cathode current collector and mitigate mechanical stresses during the formation of a cylindrical jelly roll. Lithium-sulfur batteries including thick cathodes.

Abstract: 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.
