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: 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.
