Abstract: A nanoparticle or agglomerate which contains connected multi-walled spherical fullerenes coated in layers of graphite. In different embodiments, the nanoparticles and agglomerates have different combinations of: a high mass fraction compared to other carbon allotropes present, a low concentration of defects, a low concentration of elemental impurities, a high Brunauer, Emmett and Teller (BET) specific surface area, and/or a high electrical conductivity. Methods are provided to produce the nanoparticles and agglomerates at a high production rate without using catalysts.

Abstract: A composition of matter suitable for usage as a formative material for a lithium-sulfur battery cathode is provided. The composition of matter may include a carbon structure formed by multiple carbon particles interconnected to one another. Each carbon particle may include pores and exposed surfaces. In this way, an electrically conductive material (ECM) (e.g., silver and/or antimony) may be deposited in the pores and coated (e.g., conformally coated) on the exposed surfaces of respective carbon particles. In addition, at least some carbon particles may disintegrate and provide exposed surfaces prior to deposition of the ECM. For example, disintegrated carbon particles may have a greater surface-area-to-volume ratio than whole carbon particles, thereby providing an increased amount of surface area available for subsequent ECM deposition. In addition, in some aspects, an active material may be infiltrated in one or more carbon particles and pores.

Abstract: This disclosure provides an electrode having a carbon-based structure with a plurality of localized reaction sites. An open porous scaffold is defined by the carbon-based structure and can confine an active material in the localized reaction sites. A plurality of engineered failure points is formed throughout the carbon-based structure and can expand in a presence of volumetric expansion associated with polysulfide shuttle. The open porous scaffold can inhibit a formation of interconnecting solid networks of the active material between the localized reaction sites. The plurality of engineered failure points can relax or collapse during an initial activation of the electrode. The open porous scaffold can define a hierarchical porous compliant cellular architecture formed of a plurality of interconnected graphene platelets fused together at substantially orthogonal angles. The hierarchical porous compliant cellular architecture can be expansion-tolerant and can expand in a presence of Li ion insertion or de-insertion.

Abstract: Microwave chemical processing system having a microwave plasma reactor, and a multi-stage gas-solid separation system are disclosed. The microwave energy source has a waveguide, a reaction zone, and an inlet configured to receive the input material, and the input material is converted into separated components. The separated components include hydrogen gas and carbon particles. The multi-stage gas-solid separation system has a first cyclone separator to filter the carbon particles from the separated components, and a back-pulse filter system coupled to the output of the first cycle separator to filter the carbon particles from the output from the first cyclone separator.
