1. A process of forming an electrochromic stack, the process comprising:
depositing, at an electrode station, at least a portion of an electrochromic electrode (EC) layer of an electrochromic stack;
depositing, at a single metallic lithium station, metallic lithium onto the electrochromic EC layer deposited at the electrode station; and
depositing, at a counter-electrode station, an electrochromic counter-electrode (CE) layer of the electrochromic stack utilizing a lithium-containing ceramic counter-electrode target.
