  • Publication number: 20160190600
    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.

  • Patent number: 9287137
    Abstract: Embodiments of the disclosure generally provide methods of forming a silicon containing layers in TFT devices. The silicon can be used to form the active channel in a LTPS TFT or be utilized as an element in a gate dielectric layer, a passivation layer or even an etch stop layer. The silicon containing layer is deposited by a vapor deposition process whereby an inert gas, such as argon, is introduced along with the silicon precursor. The inert gas functions to drive out weak, dangling silicon-hydrogen bonds or silicon-silicon bonds so that strong silicon-silicon or silicon-oxygen bonds remain to form a substantially hydrogen free silicon containing layer.

  • Patent number: 9254505
    Abstract: A variety of methods, devices, systems and arrangements are implemented involving nanowire meshes. One such method is implemented to include synthesizing metal nanowires in a solution containing a structure-directing agent. The metal nanowires are deposited on a substrate to form a sheet of nanowires. The deposited metal nanowires are heated to a temperature less than about 200 degrees Celsius and for a period of time of about 10 minutes to 60 minutes, thereby removing the structure-directing agent and modifying the electrical conductivity and optical transmittance of the sheet of nanowires.

  • Patent number: 9112212
    Abstract: Provided are novel methods of fabricating electrochemical cells containing high capacity active materials that form multilayered solid electrolyte interphase (SEI) structures on the active material surface during cell fabrication. Combining multiple different SEI layers on one surface can substantially improve cell performance by providing each layer with different properties. For example, an outer layer having a high electronic resistance may be combined with an inner layer having a high ionic permeability. To form such multilayered SEI structures, formation may involve changing electrolyte composition, functionalizing surfaces, and/or varying formation conditions. For example, formation may start with a boron containing electrolyte. This initial electrolyte is then replaced with an electrolyte that does not contain boron and instead may contain fluorine additives. In certain embodiments, cell's temperature is changed during formation to initiate different chemical reactions during SEI formation.
