POSTER 1: Room-Temperature Fabrication of Dense LLZO Layer by Aerosol Deposition
Presented by Eungje L., Argonne National Laboratory
Aerosol deposition (AD) is a low-cost, scalable method that forms dense ceramic films of thickness 1-100 µm at room temperature with high film-fabrication speed (>5 µm/min). We present the development of the aerosol deposition process to fabricate a dense ceramic electrolyte (Li6.25Al0.25La3Zr2O12, LLZO) layer. The effect of AD film fabrication parameters and the physical properties of feeding powders on the quality of AD films will be discussed.

POSTER 5: Developments in Optical Characterization of Solid State Batteries
Presented by Nolan W., HORIBA Scientific
As the solid-state battery field advances, optical characterization is needed to study the electrodes and electrolytes and guide the optimization of battery performance. Spectroscopic techniques are preferred because they are non-destructive and yield compositional and structural information. In this work, we used Raman spectroscopy and elemental analysis to monitor electrode/electrolyte deterioration, evaluate spatial heterogeneity of performance/deterioration/defects (across surfaces and depth profiling of electrolytes and coatings), and perform quality control.

Presented by Yoon-Cheol H., Korea Electrotechnology Research Institute (KERI)
To control the particle size and crystallinity of sulfide solid electrolytes, a novel facile polar-to-nonpolar solvent exchange technique is introduced. Volume-confined instantaneous recrystallization enables high purity, submicron-sized SSEs with high Li-ion conductivity. In this case study, the average particle size of a commercial Li6PS5Cl SSE was reduced from 8 um to 0.88 um, and all-solid-state cells using the submicron SSE showed higher capacity and better cycle performance.

POSTER 10: Safety Standards and Solid State Batteries: Is Understanding Lithium-Ion Enough?
Presented by Lucy B., Exponent
The notoriety experienced by Solid State batteries will become critical when the technology enters the field and begins facing increased scrutiny over field failures. By some accounts, this has already begun [1,2]. To help prevent major issues, it is crucial to thoroughly evaluate new designs prior their release to the market, not only by making sure they adhere to the incumbent lithium-ion battery safety standards, but also by understanding their unique failure scenarios and the impact they could have on the end user. This poster will highlight design challenges for batteries with increased energy densities enabled by solid state cell materials, as well as methods to design for safety, including various electrochemical and calorimetric techniques.

Presented by Mahir U., Mercedes-Benz AG
Post-lithium electrochemical energy storage systems are of paramount interest for industrial application due to high performance and safety. To access the practically desired high energy density of ASSBs and enable large-scale processing, a thin solid electrolyte film with high ion-transport is mandatory to reduce the proportion of inactive materials. In this effort, a flexible, freestanding SE film based on sulfide-based argyrodite (Li[6]PS[5]Cl) is prepared through a facile, conventional wet-coating technique.

Presented by Taylor X., Navitas Systems
Dry Process electrode fabrication was demonstrated to enable large format solid-state-battery incorporating free-standing high-capacity cathode, LiPS solid-state electrolyte, and lithium anode. LiPS SSE with halogen additive showed high ionic conductivity (3-4 mS/cm) and great air stability. ASSB with flexible surface-coated NCM811 cathode, halogen stabilized SSE, and surface-protected Li demonstrated high NCM811 specific capacity (> 200 mAh/g) with coulombic efficiency > 99.5%, and it can deliver 500 Wh/kg specific energy.
POSTER 13: Compositional and Structural Control in LLZO Solid Electrolytes
Presented by Kade P., Queensland University of Technology
A novel solution-based synthesis technique is used to demonstrate the importance of precursor homogeneity in controlling the composition and structure of LLZO solid electrolytes. In-situ X-ray and neutron diffraction coupled with elemental mapping show that enhanced homogeneity at the precursor stage (1) improves dopant distribution to stabilize the conductive cubic phase, (2) mitigates local segregation to eliminate impurities and (3) improves reaction kinetics to lower the formation temperature by 250°C.
POSTER 14: Thermoplastic Solutions for Battery Enclosures
Presented by Fred C., SABIC
For EV battery pack applications, the inherent low density and design freedom of thermoplastics can reduce weight and cost through integration and consolidation of parts and features, such as molded-in cooling channels and energy/impact absorbers. Specific polypropylene and engineered thermoplastics can also meet flammability requirements. To support use of these materials for larger components, various plastic manufacturing technologies are available or under development to bring concepts to production.

POSTER 16: Glass Electrolytes
Presented by Martin M., University of Chemistry and Technology
Quenched from its melt, the fast ion-conducting glass is a "frozen" liquid of high viscosity and amorphous structure. Therefore, it can effectively work in all-solid-state batteries replacing liquid electrolytes. As a solid solution, glass properties can be continuously tailored by adjusting its composition. Composition-property models involving the effects of components save experiments. Due to large free volume and well-balanced inorganic bonds, the glass can achieve high ionic conductivity and stability.
