    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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).

    摘要： Methods include producing tunable carbon structures and combining carbon structures with a polymer to form a composite material. Carbon structures include crinkled graphene. Methods also include functionalizing the carbon structures, either in-situ, within the plasma reactor, or in a liquid collection facility. The plasma reactor has a first control for tuning the specific surface area (SSA) of the resulting tuned carbon structures as well as a second, independent control for tuning the SSA of the tuned carbon structures. The composite materials that result from mixing the tuned carbon structures with a polymer results in composite materials that exhibit exceptional favorable mechanical and/or other properties. Mechanisms that operate between the carbon structures and the polymer yield composite materials that exhibit these exceptional mechanical properties are also examined.
