Abstract: Herein are described processes for and machines adapted for the production of lithium coated conductive substrates having conductive substrate planar surfaces. The process can include providing a lithium coated conductive substrate and then calendering the coated-foil to provide the desired planar surface(s). In a preferable instance, the process provides double sided lithium carrying conducive substrates useful in lithium metal batteries. In another instance, the process provides single or double sided coated-foils carrying polymeric sheets. The machines for the production of the desired products preferably include apparatus for the deposition of lithium metal onto a conductive substrate and one or more calendering systems, preferable within a single vacuum chamber.
