Abstract: Apparatuses and methods for producing covetic materials by exciting a hydrocarbon gas with pulse microwaves to form hydrocarbon radicals in a hot first region of a microwave reactor. Graphene nanoplatelets are formed by the nucleation, growth and assembly of the hydrocarbon radicals, and contact a metal melt introduced downstream of the hot region to produce a mixture of molten metal and graphene nanoplatelets which assemble in-flight to form covetic materials. Graphene planes are infused in the metal matrix to achieve carbon loadings of at least 60%.

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: Methods include determining a desired hysteretic curve that corresponds to a set of dynamic mechanical analysis parameters, where the desired hysteretic curve comprises elastic portions and plastic portions, and the elastic and plastic portions comprise specific desired shapes. A first tuned carbon is selected, the first tuned carbon facilitating achievement of a desired shape of a particular elastic portion of the hysteretic curve. One or more selected post-treatments is performed on the first tuned carbon to form a first post-treatment carbon, the selected post-treatment facilitating achievement of a desired shape of a particular plastic portion of the hysteretic curve. The methods also include combining the first post-treatment carbon with other materials that are used in components of the tire and curing the combination comprising the first post-treatment carbon and the other materials.
