  • Publication number: 20140291144
    Abstract: A plasma chamber for depositing a battery component material on a partially fabricated battery cell comprising a battery component layer containing charge-carrying metal species and having an exposed surface. The chamber comprises a support carrier to hold a battery support comprising the partially fabricated battery cell. A mesh screen is positioned at a preset distance from the support carrier, the mesh screen having a plurality of mesh openings. An exhaust maintains a pressure of the process gas in the plasma chamber. A plasma power source is capable of applying an electrical power to the process gas to generate a plasma from the process gas for plasma deposition, during which the mesh screen is capable of reducing migration of the charge-carrying metal species across the battery component layer.
