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: This disclosure provides a tire formed of a body having multiple plies and a tread that surrounds the body. The plies and/or the treads and/or other surfaces of the tire include one or more resonators that respond to being interrogated by an externally generated excitation signal. Multiple resonators formed of electrically-conducting materials are disposed (e.g., printed) on the plies and/or tread and/or other surfaces of the tire. Each of a group of multiple resonators can be individually configured to respond to different frequencies of the excitation signal such that the presence of a response (e.g., a measured attenuation of the excitation signal return) or lack of response (e.g., based on comparison of the excitation signal return to calibration curves) from individual ones of the multiple resonators can be combined to form a serial number that is unique to the tire or other elastomer-containing component (e.g., belts, hoses, etc.) being interrogated.

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: 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.

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: A container includes a surface and an electromagnetic state sensing device including one or more resonance portions printed on the surface of the container. Each resonance portion may include an assembly of 3D carbon-containing structures that convey information of a stored item by resonating at a predetermined frequency in response to an electromagnetic radiation ping received from a user device. The resonance portions may include at least a first resonance portion configured to convey product identification information of the stored item and a second resonance portion configured to convey product state information of the stored item. The first resonance portion conveys product identification information of the stored item in response to a first electromagnetic radiation ping having a first frequency, and the second resonance portion conveys product state information of the stored item in response to a second electromagnetic radiation ping having a second frequency different than the first frequency.

Abstract: This disclosure provides a sensor for detecting an analyte. The sensor can include an antenna and sensing material both disposed on a substrate, where the sensing is electrically coupled to the antenna. The sensing material can include a carbon structure including a multi-modal distribution of pore sizes that define a surface area including bonding sites configured to interact with one or more additives and the analyte. The carbon structure is configured to generate a resonant signal indicative of one or more characteristics of the analyte in response to an electromagnetic signal. The carbon structure can include distinctly sized interconnected channels defined by the surface area and configured to be infiltrated by the analyte, and exposed surfaces configured to adsorb the analyte. Each of the interconnected channels can include microporous pathways and/or mesoporous pathways, which can increase a responsiveness of the sensing material proportionate to the analyte within the carbon structure.
