This first-of-its-kind system enables the deposition of thin film SSB cathode oxides, solidelectrolyte oxides and nitrides, and metallic anodes (contact layers) with atomic precision andwithout breaking vacuum conditions. Moreover, the system enables inert transfer of the depositedfull cell to a glovebox for degradation analysis, characterization, and performance testing withoutever exposing the SSN to atmospheric conditions. The three component system combines: 1)pulsed laser deposition (PLD) for the oxide cathode and solid electrolyte (SE) deposition, 2) metalevaporation for anode (Li, Na) deposition, and 3) a glove box for inert atmosphere measurementand testing. All three components are connected via load locks and transfer arms to mitigate airexposure of each component and ensure high quality interfaces. The deposition proposed here cansynthesize full dense and single crystal SSB heterostructure components with a high control(atomically precise control) over SSB interfaces. The dedicated battery synthesis branches of thesystem include novel substrate heatingand load locks. Additionally, they contain combinatorialgrowth capabilities which minimize cross contamination, maximize stoichiometric film quality,and allow for high throughput synthesis. Both the strain (via electron diffraction) and the stress(via multibeam optical sensors) can be measured in-situ during battery deposition to verifymechanical and epitaxial properties of each SSB. The inert atmosphere glovebox will be used tocyclic battery testing and electrical measurements to verify engineered battery safety, stability,capacity, and fatigue.The proposed system is the first deposition tool to our knowledge that can synthesize full or partialcell SSB and test their efficacy of the SSB in naval applications without exposure to air. Thesystem will enable rapid development on the funded ONR award #N00014-23-1-2688, one of thegoals of which is to develop stress-engineered solid electrolytes to suppress dendritenucleationand growth in Li-ion batteries. The facility will also nucleate new synergies and collaborationswith other researchers inONR#s power and energy for undersea applications portfolio and willserve as a resource for the entire ONR research community pursuing solid state battery research.
