Abstract
A plasma deposition method deposits 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. A mesh screen is maintained at a preset distance from the exposed surface, the mesh screen having a plurality of mesh openings. A process gas is energized to form a plasma by applying an electrical power to deposit the battery component material onto the exposed surface of the battery component layer. The mesh screen reduces migration of the charge-carrying metal species in the battery component layer to the exposed surface of the partially fabricated battery cell.
