    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 composition of matter may include pores and non-tri-zone particles and tri-zone particles. In one implementation, each tri-zone particle may include carbon fragments intertwined with each other and separated from one another by mesopores. Each tri-zone particle may also include a deformable perimeter that may coalesce with adjacent non-tri-zone particles or tri-zone particles. In some aspects, the tri-zone particles may include aggregates formed by a multitude of the tri-zone particles joined together. In some aspects, mesopores may be interspersed throughout the aggregates. Each tri-zone particle may also include agglomerates, where each agglomerate includes a multitude of the aggregates joined together. In some aspects, macropores may be interspersed throughout the aggregates.

    Abstract: Batteries including an electrolyte with a ternary solvent package are disclosed. In various implementations, a lithium-sulfur battery may include a cathode, an anode, and an electrolyte include a ternary solvent package. The anode may be positioned opposite to the cathode. The cathode may include a plurality of regions. Each region may be defined by two or more core-shell structures adjacent to and in contact with each other. The electrolyte may be interspersed throughout the cathode and be in contact with the anode. The ternary solvent package may include 1,2-Dimethoxyethane (DME), 1,3-Dioxolane (DOL), tetraethylene glycol dimethyl ether (TEGDME), and/or one or more additives, such as lithium nitrate (LiNO3), and 4,4′-thiobisbenzenethiol (TBT) or 2-mercaptobenzothiazole (MBT), and approximately 0.01 mol of dissolved lithium bis(trifluoromethanesulfonyl)imide (LiTFSI).

    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.

    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: An lithium-sulfur battery including an anode, a cathode, and a solid-state electrolyte is provided. The anode may be formed as a single layer of lithium and/or as a cavity. In some aspects, the cavity may receive lithium deposits based on lithium output from the cathode. The cathode may be formed from a composition of matter including pores. A solid-state electrolyte may be dispersed throughout the cathode and in contact with the anode. The solid-state electrolyte may be formed as a membrane and may provide ionic conduction capabilities associated with a separator. The solid-state electrolyte includes a polymer matrix formed of glass fibers interconnected with each other. The polymer matrix has an ionic conductivity and includes polyethylene oxide (PEO), polyvinylidene difluoride (PVDF), polyetheramine having repeated oxypropylene units in its backbone, and one or more lithium-containing salts including one or more of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) or lithium iodide (LiI).
