摘要： A multistage centrifugal atomizer comprises an outer shell that contains an inlet port and an outlet port and that encloses a tundish, a first inclined rotating surface and a second inclined rotating surface. The first inclined rotating surface is opposedly disposed to the second inclined rotating surface. The inlet is used to introduce a molten material into the multistage atomizer and the outlet is used to remove ultrafine particles having a D50 of less than 20 micrometers.

摘要： An electroactive material for use in an electrochemical cell, like a lithium ion battery, is provided. The electroactive material comprises silicon or tin and undergoes substantial expansion during operation of a lithium ion battery. A polymeric ultrathin conformal coating is formed over a surface of the electroactive material. The coating is flexible and is capable of reversibly elongating by at least 250% from a contracted state to an expanded state in at least one direction to minimize or prevent fracturing of the negative electrode material during lithium ion cycling. The coating may be applied by vapor precursors reacting in atomic layer deposition (ALD) to form conformal ultrathin layers over the electroactive materials. Methods for making such materials and using such materials in electrochemical cells are likewise provided.

摘要： Systems, methods, and high performance electrochemical devices employing electroactive particles having a sandwich structure are described. The electroactive particle includes an electroactive layer between a pair of dimension-control layers. The electroactive layer includes an electroactive material configured to receive cations and experience a volumetric change in response thereto. The dimension-control layers are configured to inhibit planar dimensional changes of the electroactive particle such that the volumetric change of the electroactive layer occurs through a vertical dimension of the electroactive particle. The vertical dimension is orthogonal to the planar dimensions.

摘要： A lamp assembly includes a housing forming an interior space, and having a first portion and a second portion. A light source is disposed within the interior space and positioned to direct light through the first portion. An electrically resistive coating is disposed on the first portion of the housing, and is operable to heat the first portion to create a positive temperature gradient in which the first portion exhibits a higher temperature than the second portion so that moisture within the interior space condenses on the second portion and not the first portion. A self-contained power supply, including an energy storage device and a solar cell, may be incorporated into the housing. An interior surface of the first portion may be coated with a hydrophobic coating, and an interior surface of the second portion may be coated with a hydrophilic coating.

摘要： A positive electrode includes a lithium-based active material, a binder, a conductive filler, and discrete aluminum oxide nanomaterials. The aluminum oxide nanomaterials are mixed, as an additive, throughout the positive electrode with the lithium-based active material, the binder, and the conductive filler. The positive electrode with the discrete aluminum oxide nanomaterials may be incorporated into a lithium ion battery. The aluminum oxide nanomaterials may be formed by the following method. A solution is formed by mixing an aluminum oxide precursor and an acid. A carbon material is added to the solution, thereby forming an aqueous mixture having the carbon material therein. Hydrothermal synthesis is performed using the aqueous mixture, and precursor nanostructures are grown on the carbon material. The precursor nanostructures on the carbon material are annealed so that the carbon material is removed and aluminum oxide nanomaterials are formed.

摘要： Methods for making a negative electrode material for use in an electrochemical cell, like a lithium ion battery, are provided. The electroactive material comprises silicon. The electroactive material comprises a functionalized surface having a grafted reactive group (e.g., an epoxide group, an amino group, a carboxyl group, and the like). The functionalized surface is admixed and reacted with a polymeric binder (e.g., polyalkylene oxide (PAO), polyvinylidene difluoride (PVDF), polymethylmethacrylate (PMMA), polyimide (PI), and the like that also has at least one reactive functional group) and optionally electrically conductive particles. A porous solid electrode material is thus formed. Negative electrodes are also provided, which provide significant performance benefits and reduce the issues associated with capacity fade, diminished electrochemical cell performance, cracking, and short lifespan associated with conventional silicon anode materials.
