Solid-state batteries (SSBs) represent the next frontier in energy storage, offering unmatched safety and high energy density. At the heart of this technology lies a critical manufacturing challenge: creating flawless, ultra-dense electrodes. Unlike conventional batteries, SSBs depend on perfect solid-to-solid particle contact, where any void or gap dramatically increases internal resistance and risks cell failure.
This technical webinar delves into the critical relationship between the physical properties of raw materials and the final microstructure of solid-state electrodes. We will explore how fundamental parameters such as particle size distribution (PSD) and powder packing density of both cathode active materials and solid electrolytes directly impact ionic conductivity, dendrite suppression, and the ultimate volumetric energy density of the cell.

More About the Webinar
Attendees will gain actionable insights into how data obtained from advanced analytical techniques, such as laser diffraction and density analysis (true and tapped), can be utilized to monitor, predict, and control these parameters. This data-driven approach is essential for enhancing production efficiency, minimizing defects, and ensuring consistent, high-performance battery quality.
Recognizing the challenge of handling highly air- and moisture-sensitive materials, such as sulfide electrolytes, this session will also showcase Bettersize's complete workflow for safe and accurate characterization. We will feature the Bettersizer 2600 with its full glovebox integration solution, designed to protect both sample integrity and operator safety. This integrated system is complemented by the BetterPyc for precise true density measurement and the BeDensiTPro series for essential powder packing analysis. Whether you are in R&D or scaling up production, this webinar offers vital, practical insights for optimizing your SSB materials and manufacturing processes.
