The present disclosure describes various processes of forming an electrochromic stack using at most one metallic lithium deposition station. In some aspects, a process may include depositing metallic lithium only within an electrochromic counter-electrode of an electrochromic stack. In some aspects, a process may include using a lithium-containing ceramic counter-electrode target to form an electrochromic counter-electrode and depositing metallic lithium only within or above an electrochromic electrode of the electrochromic stack. In some embodiments, a process may include using a lithium-containing ceramic electrode target, and optionally additionally depositing metallic lithium to add mobile lithium to the electrochromic stack. In some embodiments, a process may include using a single metallic lithium deposition station to deposit metallic lithium between an ion-conducting layer and an electrochromic electrode of the electrochromic stack.

An article can include a non-light-emitting, variable transmission device and a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article. In an embodiment, the article has a &#x394;E of at most 6.5. In another embodiment, the coating includes a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of at least 10 nm. The coating can be used to help reduce color differences seen when the non-light-transmitting, variable transmission device is taken to different transmission states. In a particular embodiment, the coating can provide a good balance between color difference and luminous transmission.
