Advanced Anode Manufacturing through Ultra-Thin Li Deposition
During the program's tenure, Applied Materials delivered high-quality (>99.9%) ultra-pure thin lithium metal in sheets and in roll to roll (R2R) formats to program partners for testing, cell builds and evaluation. The thickness range of the deposited Lithium can be controlled between 1-20 μm (<3% nonuniformity). A second R2R tool was commissioned for Li processing and inline CO 2 passivation module was validated. Additionally, S2S deposition tools were used to explore five different surface protection materials for Li-metal. One surface passivation chemistry was down selected for testing and showed improved performance. Key results are summarized in this final report.
