Patent ID: 8753724

Claim:
A plasma deposition method for depositing a battery component material on a partially fabricated battery cell in a plasma deposition zone, the method comprising: (a) providing in the plasma deposition zone, a battery support comprising at least one partially fabricated battery cell, the partially fabricated battery cell comprising a battery component layer containing charge-carrying metal species and having an exposed surface; (b) maintaining a mesh screen spaced apart, and at a preset distance from, the exposed surface of the battery component layer of the partially fabricated battery cell, the mesh screen having a plurality of mesh openings; (c) maintaining a pressure of a process gas in the plasma deposition zone; and (d) energizing the process gas to form a plasma by applying an electrical power to the process gas to deposit the battery component material onto the exposed surface of the battery component layer, whereby the mesh screen reduces migration of the charge-carrying metal species across the battery component layer.
