A coating layer for a substrate includes a coating material. The coating material includes graphene and/or graphene derivatives that reflect and/or absorb an electromagnetic (EM) wave having a frequency of above 20 GHz. The coating layer is deposited on a surface of the substrate.

Graphene and graphene derivatives as substrate coatings

Provided herein are high throughput continuous or semi-continuous reactors and processes for manufacturing graphenic materials, such as graphene. Such processes are suitable for manufacturing graphenic materials at rates that are up to hundreds of times faster than conventional techniques, and have little batch-to-batch variation. Also provided herein are graphenic compositions of matter, including large, high quality and/or highly uniform graphene.

Continuous manufacture of graphenic compounds

Provided herein are high performance electrodes, electrode materials comprising a plurality of active electrode material-containing particles secured within one or more graphenic web, and precursors thereof. Also provided herein are processes of generating the same by an electrospray process.

High performance electrodes, materials, and precursors thereof

Provided in certain embodiments are high performance graphene fibers and yarns, including components and precursors thereof, and composites comprising the same. Also provided herein are methods of manufacturing such fibers, yarns, composites, and components/precursors thereof.

Graphenic fibers, yarns, composites, and methods of making the same

Provided herein are nanofibers and processes of preparing nanofibers. In some instances, the nanofibers are metal and/or ceramic nanofibers. In some embodiments, the nanofibers are high quality, high performance nanofibers, highly coherent nanofibers, highly continuous nanofibers, or the like. In some embodiments, the nanofibers have increased coherence, increased length, few voids and/or defects, and/or other advantageous characteristics. In some instances, the nanofibers are produced by electrospinning a fluid stock having a high loading of nanofiber precursor in the fluid stock. In some instances, the fluid stock comprises well mixed and/or uniformly distributed precursor in the fluid stock. In some instances, the fluid stock is converted into a nanofiber comprising few voids, few defects, long or tunable length, and the like.

Metal and ceramic nanofibers

Provided in certain embodiments herein are alternating current electrospray systems and processes for manufacturing depositions, such as thin layer depositions. In some embodiments, processes and systems provided herein are suitable for and configured to manufacture uniform depositions, such as having uniform thickness.

Alternating current electrospray manufacturing and products thereof

Described herein are nanofibers and methods for making nanofibers that include any one or more of (a) a non-homogeneous charge density; (b) a plurality of regions of high charge density; and/or (c) charged nanoparticles or chargeable nanoparticles. In one aspect, the present invention fulfills a need for filtration media that are capable of both high performance (e.g., removal of particle sizes between 0.1 and 0.5 &#x3bc;m) with a low pressure drop, however the invention is not limited in this regard.

Charged nanofibers and methods for making

Provided herein are positive electrodes for lithium batteries, particularly lithium sulfur batteries, and the manufacture thereof. Particularly, such electrodes have good performance characteristics, such as capacity and capacity retention, even at very high loading of sulfur (e.g., &#x3e;5 mg/cm2), as well as flexibility. Exemplary manufacturing techniques include the electrospraying of sulfur (e.g., electrode active sulfur compounds), and an optional additive (e.g., a nanostructured conductive additive), onto a porous, conductive substrate (e.g., a porous carbon substrate, such as comprising multiple layers and/or domains).

Multi-domained sulfur electrodes, and manufacturing therefor

Provided herein are ceramic nanofibers and processes for preparing the same. In specific examples, provided herein are ceramic nanofiber mats for use as separators in batteries, particularly lithium ion batteries. In some embodiments, the separators described herein may include a nanofiber mat including at least one nanofiber having a continuous matrix material.

Ceramic nanofiber separators

Lithium ion batteries, electrodes, nanofibers, and methods for producing same are disclosed herein. Provided herein are batteries having (a) increased energy density; (b) decreased pulverization (structural disruption due to volume expansion during lithiation/de-lithiation processes); and/or (c) increased lifetime. In some embodiments described herein, using high throughput, water-based electrospinning process produces nanofibers of high energy capacity materials (e.g., ceramic) with nanostructures such as discrete crystal domains, mesopores, hollow cores, and the like; and such nanofibers providing reduced pulverization and increased charging rates when they are used in anodic or cathodic materials.

Lithium ion batteries comprising nanofibers

Provided herein are high throughput continuous or semi-continuous reactors and processes for manufacturing graphenic materials, such as graphene oxide. Such processes are suitable for manufacturing graphenic materials at rates that are up to hundreds of times faster than conventional techniques, have little batch-to-batch variation, have a high degree of tunability, and have excellent performance characteristics.

Provided herein are a variety of electrolytes, electrolyte systems, and separator systems, as well as batteries comprising the same and precursors thereof. In specific embodiments are semi-solid or gel electrolytes, particularly those prepared using (i) a cross-linkable polysilsesquioxane with high ionic conductivity and (ii) a liquid electrolyte (e.g., ionic liquid).

Gel electrolytes and the manufacture thereof

Provided in certain embodiments herein are gas controlled electrospray systems and processes for manufacturing depositions, such as thin layer films. In some embodiments, processes and systems provided herein are suitable for and configured to manufacture uniform depositions, such as having uniform thickness.

Air controlled electrospray manufacturing and products thereof
