Abstract: Provided are various examples of lithium electrode subassemblies, lithium ion cells using such subassemblies, and methods of fabricating such subassemblies. Methods generally include receiving nanostructures containing electrochemically active materials and interconnecting at least a portion of these nanostructures. Interconnecting may involve depositing one or more interconnecting materials, such as amorphous silicon and/or metal containing materials. Interconnecting may additionally or alternatively involve treating a layer containing the nanostructures using various techniques, such as compressing the layer, heating the layer, and/or passing an electrical current through the layer. These methods may be used to interconnect nanostructures containing one or more high capacity materials, such as silicon, germanium, and tin, and having various shapes or forms, such as nanowires, nanoparticles, and nano-flakes.

Abstract: Electrochemical cells containing nanostructured negative active materials and composite positive active materials and methods of fabricating such electrochemical cells are provided. Positive active materials may have inactive components and active components. Inactive components may be activated and release additional lithium ions, which may offset some irreversible capacity losses in the electrochemical cells. In certain embodiments, the activation releases lithium ion having a columbic content of at least about 400 mAh/g based on the weight of the activated material.

Abstract: Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.

Abstract: Provided are novel electrodes for use in lithium ion batteries. An electrode includes one or more intermediate layers positioned between a substrate and an electrochemically active material. Intermediate layers may be made from chromium, titanium, tantalum, tungsten, nickel, molybdenum, lithium, as well as other materials and their combinations. An intermediate layer may protect the substrate, help to redistribute catalyst during deposition of the electrochemically active material, improve adhesion between the active material and substrate, and other purposes. In certain embodiments, an active material includes one or more high capacity active materials, such as silicon, tin, and germanium. These materials tend to swell during cycling and may loose mechanical and/or electrical connection to the substrate. A flexible intermediate layer may compensate for swelling and provide a robust adhesion interface. Provided also are novel methods of fabricating electrodes containing one or more intermediate layers.

Abstract: Provided are novel negative electrodes for use in lithium ion cells. The negative electrodes include one or more high capacity active materials, such as silicon, tin, and germanium, and a lithium containing material prior to the first cycle of the cell. In other words, the cells are fabricated with some, but not all, lithium present on the negative electrode. This additional lithium may be used to mitigate lithium losses, for example, due to Solid Electrolyte Interphase (SEI) layer formation, to maintain the negative electrode in a partially charged state at the end of the cell discharge cycle, and other reasons. In certain embodiments, a negative electrode includes between about 5% and 25% of lithium based on a theoretical capacity of the negative active material. In the same or other embodiments, a total amount of lithium available in the cell exceeds the theoretical capacity of the negative electrode active material.

Abstract: Provided are conductive substrates having open structures and fractional void volumes of at least about 25% or, more specifically, or at least about 50% for use in lithium ion batteries. Nanostructured active materials are deposited over such substrates to form battery electrodes. The fractional void volume may help to accommodate swelling of some active materials during cycling. In certain embodiments, overall outer dimensions of the electrode remain substantially the same during cycling, while internal open spaces of the conductive substrate provide space for any volumetric changes in the nanostructured active materials. In specific embodiments, a nanoscale layer of silicon is deposited over a metallic mesh to form a negative electrode. In another embodiment, a conductive substrate is a perforated sheet with multiple openings, such that a nanostructured active material is deposited into the openings but not on the external surfaces of the sheet.

Abstract: Provided are electrode layers for use in rechargeable batteries, such as lithium ion batteries, and related fabrication techniques. These electrode layers have interconnected hollow nanostructures that contain high capacity electrochemically active materials, such as silicon, tin, and germanium. In certain embodiments, a fabrication technique involves forming a nanoscale coating around multiple template structures and at least partially removing and/or shrinking these structures to form hollow cavities. These cavities provide space for the active materials of the nanostructures to swell into during battery cycling. This design helps to reduce the risk of pulverization and to maintain electrical contacts among the nanostructures. It also provides a very high surface area available ionic communication with the electrolyte. The nanostructures have nanoscale shells but may be substantially larger in other dimensions.

The service designer is provided with a tool to choose a geographic region or a point location (specified by an address), and to associate that selected geographic region with a service. Each service is associated with a geographic region chosen from a hierarchy of predetermined system-defined regions that are preferably organized into a hierarchy composed of levels organized in order of decreasing size so that the boundaries of each child region lie within the boundaries of its parent region. The services designer is also provided with the option of creating “user defined regions” that are composed of existing system defined regions or a region centered around a selected location.

Abstract: A video signal is compressed by alternately removing predetermined arrangements of pixels, e.g. odd and even lines. In the case of an interlaced video signal, this may comprise removing the even fields of odd frames and odd fields of even frames. Two such compressed signals may be combined and transmitted in a channel having a bandwidth sufficient for one uncompressed signal only. In the case of non-interlaced video signals, odd and even lines, for example, may be removed from alternate frames. The removed lines can be replaced with odd and even lines taken from another video signal to produce a compressed video signal in which the lines are alternately from first and second uncompressed video signals.
