Abstract
CSEM aims at developing alternative high-quality and cost-effective methods for the fabrication of lithium metal (LiM) anodes to improve performances and safety of LiM batteries. Two are the main technologies under development: (i) Thin LiM deposition via thermal evaporation process, which possess better properties (e.g., roughness, homogeneity, thickness, cycle life, etc.) compared to the commercial extruded lithium, and (ii) Thin film coating solutions. Cycling data show an increase in cycle life of batteries with coated LiM anode by a factor 2x when compared to the ones with uncoated LiM.
