Abstract
Aspects of the disclosure include a thickness control manifold for molten lithium dip coating. An exemplary thickness control manifold includes a plurality of rollers positioned to guide a current collector from a feed roller to a molten lithium bath and to provide a vertical current collector pull from the molten lithium bath. A gas knife is positioned after the vertical current collector pull and against a side of the current collector. The manifold includes a cold gas tip having a first gas port and a first gas channel that is positioned to eject a cooled fluid to the side of the current collector and a hot gas tip having a second gas port and a second gas channel that is positioned to eject a heated fluid to the side of the current collector. The hot gas tip is between the cold gas tip and the molten lithium bath.
