Method of manufacturing an anode structure, vacuum deposition system, anode structure, and lithium battery layer stack

A vacuum deposition system for manufacturing an anode structure, comprising:

• a first lithium deposition apparatus for depositing a lithium anode-first sublayer with a first lithium surface on a first flexible support;
• a second lithium deposition apparatus for depositing a lithium anode-second sublayer with a second lithium surface on a second flexible support;
• and
• a combining device for combining the lithium anode-first sublayer and the lithium anode-second sublayer by pressing the first lithium surface and the second lithium surface together to form a lithium metal anode layer.

A lithium battery layer stack, comprising:

• a cathode current collector,
• a cathode on the cathode current collector,
• a separator or a solid state electrolyte layer on the cathode current collector,
• a lithium metal anode layer on the separator or solid state electrolyte layer, and
• an anode current collector on the lithium metal anode layer,
• wherein the lithium metal anode layer is a pure lithium film in direct contact with both the anode current collector and the separator or solid state electrolyte layer.
