  • PLATING TECHNIQUE FOR ELECTRODE
    Publication number: 20170141402
    Abstract: Articles and methods for forming protected electrodes for use in electrochemical cells, including those for use in rechargeable lithium batteries, are provided. In some embodiments, the articles and methods involve an electrode that does not include an electroactive layer, but includes a current collector and a protective structure positioned directly adjacent the current collector, or separated from the current collector by one or more thin layers. Lithium ions may be transported across the protective structure to form an electroactive layer between the current collector and the protective structure. In some embodiments, an anisotropic force may be applied to the electrode to facilitate formation of the electroactive layer.
