Dielectric coated lithium metal anode

A method, comprising:

• transferring a flexible substrate from a storage spool in a first spool chamber to a first deposition chamber arranged downstream from the first spool chamber, the first deposition chamber comprising a first coating drum capable of guiding the flexible substrate past a first plurality of deposition units, wherein the flexible substrate comprises an anode film;
• guiding the flexible substrate past the first plurality of deposition units while depositing a lithium metal film on the anode film via the first plurality of deposition units;
• transferring the flexible substrate from the first deposition chamber to a second deposition chamber through a connection chamber, the second deposition chamber comprising a second coating drum capable of guiding the flexible substrate past a second deposition unit comprising an evaporation crucible;
• and
• guiding the flexible substrate past the evaporation crucible while depositing a ceramic protective film on the lithium metal film via the evaporation crucible.
