Application: Lithium anode device stack manufacturing (Patent ID: US20240145763A1)
The patent filed by Applied Materials Inc. pertains to anode electrode structures for high-performance electrochemical devices, specifically lithium-containing anodes in secondary batteries. The structure includes a current collector made of copper, a lithium metal film, a copper film, and a protective film that is a lithium-ion conducting film. The protective film can be made of lithium-ion conducting ceramic, glass, or liquid crystal, providing enhanced performance and stability to the electrode.
The claims detail variations in the composition and thickness of the components, such as the lithium-ion conducting film comprising materials like aluminum oxide, LiPON, and LLZO, and the thickness of the copper film. The patent also covers different configurations of the current collector, including those with nickel or chromium-containing films and polyethylene terephthalate (PET) polymer substrates. By specifying the range of thicknesses for each layer and the materials used, the patent aims to optimize the performance and longevity of the anode electrode structure in lithium-containing high-performance electrochemical devices.
