  • Publication number: 20120276449
    Abstract: Provided is an anode for use in electrochemical cells, wherein the anode active layer has a first layer comprising lithium metal and a multi-layer structure comprising single ion conducting layers and polymer layers in contact with the first layer comprising lithium metal or in contact with an intermediate protective layer, such as a temporary protective metal layer, on the surface of the lithium-containing first layer. Another aspect of the invention provides an anode active layer formed by the in-situ deposition of lithium vapor and a reactive gas. The anodes of the current invention are particularly useful in electrochemical cells comprising sulfur-containing cathode active materials, such as elemental sulfur.

  • Publication number: 20120043940
    Abstract: Electrode protection in electrochemical cells, and more specifically, electrode protection in both aqueous and non-aqueous electrochemical cells, including rechargeable lithium batteries, are presented. In one embodiment, an electrochemical cell includes an anode comprising lithium and a multi-layered structure positioned between the anode and an electrolyte of the cell. A multi-layered structure can include at least a first single-ion conductive material layer (e.g., a lithiated metal layer), and at least a first polymeric layer positioned between the anode and the single-ion conductive material. The invention also can provide an electrode stabilization layer positioned within the electrode, i.e., between one portion and another portion of an electrode, to control depletion and re-plating of electrode material upon charge and discharge of a battery.

  • Publication number: 20120040100
    Abstract: A process for planarizing a substrate involves applying a coating of a first solution of yttrium oxide precursor to a rough substrate surface and heating to remove solvent and convert the yttrium oxide precursor to yttrium oxide. This is repeated with the first solution and then with the second solution. A final surface roughness less than 1 nm RMS may be obtained. In addition, a process for preparing a layered structure includes solution deposition planarization of a rough substrate using different concentrations of metal oxide precursor to provide a metal oxide surface having a surface roughness, and then depositing MgO by IBAD (ion beam assisted deposition). A benefit of a better in plane MgO texture was observed for lower molarities, and when two solutions of different concentrations was employed for coating the rough substrate prior to IBAD-MgO.
