A method and system for fabricating a pre-lithiated electrode structure are provided. The method includes supplying a first continuous web substrate from an unwinder roller to a winder roller. The first continuous web substrate includes a layer of lithium metal. The method further includes supplying a second continuous web substrate comprising a layer of patterned anode material adjacent to the first continuous web substrate. The first continuous web substrate and the second continuous web substrate are wound together on the unwinder roller, wherein a surface of the layer of anode material contacts a surface of the layer of lithium metal. Pressure is applied to the first continuous web substrate and the second continuous web substrate to pre-lithiate the patterned anode material, wherein applying pressure comprises tensioning at least one of the unwinder roller and the winder roller.

Inline contact pre-lithiation

Exemplary processing methods may include translating a lithium film beneath a first showerhead. The methods may include introducing an oxidizer gas through the first showerhead onto the lithium film. The methods may include forming an oxide monolayer on the lithium film. The oxide monolayer may be or include the oxidizer gas adsorbed on the lithium film. The methods may include translating the lithium film beneath a second showerhead after forming the oxide monolayer. The methods may include introducing a carbon source gas through the first showerhead onto the lithium film. The methods may also include converting the oxide monolayer into a carbonate passivation layer through reaction of the oxide monolayer with the carbon source gas.
