    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 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.

    Abstract: A battery may include an anode, a cathode positioned opposite to the anode, a separator positioned between the anode and the cathode, an electrolyte dispersed throughout the cathode and in contact with the anode, and a dual-pore system. The anode may be configured to release a plurality of lithium ions. The cathode may include a plurality of pathways defined by a plurality of porous non-hollow carbonaceous spherical particles and may include a plurality of carbonaceous structures each based on a coalescence of a group of the porous non-hollow carbonaceous spherical particles. The dual-pore system may be disposed in the cathode and defined in shape and orientation by the plurality of carbonaceous structures. In some aspects, the dual-pore system may be configured to receive gaseous oxygen from the ambient atmosphere.
