Application: Integrated lithium deposition with protective layer tool (Patent ID: US20240030417A1)
The patent filed by Applied Materials Inc. describes an integrated processing tool for depositing and processing lithium metal in energy storage devices. The tool includes chambers for depositing a thin film of lithium metal and a protective film on a continuous sheet of material, potentially a web tool. The method involves forming a negative electrode by depositing a lithium metal film, an interface film, and a protective film, with various options for the interface film and protective film materials.
The method outlined in the patent involves forming a negative electrode by depositing a lithium metal film on a flexible conductive substrate, followed by the application of an interface film and a protective film. The process can be carried out using physical vapor deposition techniques and includes options for the materials used in the interface and protective films. The thickness of the lithium metal film is specified, and the protective film can be a lithium-ion conducting material or other specific materials.
