Chicago Future Manufacturing Seminar Series: Towards Sustainable and Scalable Manufacturing of Solid-State Batteries

The development of future energy storage systems relies on manufacturing materials and devices with significantly improved performance, lower cost, and reduced carbon footprint. While solid-state batteries hold great promise as the next generation of battery technology, their manufacturing remains a critical challenge. The instability of electrode and electrolyte materials as well as their chemical and electrochemical incompatibility make cell fabrication difficult, which often leads to poor battery performance and cycling stability. In this talk, we will mainly discuss our recent studies on addressing the manufacturing challenges facing solid-state batteries. Solution-based fabrication process will be compared with dry (solvent-free) process to determine some of key process parameters for both solid-state electrolytes and electrodes. Air-stability and degradation mechanisms will be systematically studied among the Li- and Na-based chemistries. In addition, we will also introduce a potential pathway to close the loop from manufacturing to recycling of solid-state batteries. Our understanding could offer some useful insights towards developing sustainable processes for solid-state battery manufacturing.
