Lamination technologies used to produce lithium ion batteries are limited by the capital investment needed for multiple unit operations, solvent use for electrolyte and electrode slurries, and an inability to exert control over active material particle morphology and homogeneity. Advancements in thin-film solid-state processing using vacuum coating hold promise to overcome these challenges for batteries with superior energy density and cycle life, if cost and scalability issues can be overcome. A comparative life cycle assessment is reported for battery production using lamination and thin-film vacuum vapor deposition. Lithium vanadium oxide solid-state cells are found to have the lowest impact, per unit energy storage, in cumulative energy demand (CED), global warming potential (GWP), and six other midpoint environmental indicators. Human health and resource depletion impacts are generally higher for lithium manganese oxide and lithium cobalt oxide solid-state cells than for their laminated counterparts, whereas CED and GWP per unit energy storage are 25-65% lower for solid-state cells across all cathode chemistries. Sensitivity analysis, taking into account uncertainties related to solid-state cell properties and vacuum vapor deposition process efficiencies, indicates that CED and GWP impacts for battery electric vehicle mobility using packs with solid-state cells will be lower than those incurred using laminated cells.
