Symposium EN06—Solid-State Batteries—From Electro-Chemo Mechanics to Devices

Solid-state battery (SSB) research has experienced an explosion worldwide, driven by increased demand for advanced electric vehicle batteries. However, there are many practical and fundamental challenges in the SSB development, which requires a balance of performance metrics,safety, and compatibility with existing manufacturing techniques. Fundamentally, SSBs present different challenges than liquid electrolyte systems, owing to additional mechanical constraints imposed by the solid electrolyte and the distinctive properties of multiple interfaces and interphases. Commercial adoption of SSBs has thus been hindered at least by limited understanding of the complex interplay between electrochemical stability, interfacial phenomena, morphological evolution, and mechanical degradation.

In this symposium, we aim to bring researchers from academia and industry together to share a vision of how practical challenges can be overcome through materials and device design that is informed by critical insights obtained from experiments, simulations, and theories. The symposium thus will bring together researchers working on these aspects, with an emphasis on critical design principles of advanced SSBs. A key focus of the symposium is to develop an integrated and interdisciplinary understanding of coupled electro-chemo-mechanical phenomena in SSBs. All forms of solid electrolytes will be considered, including ceramics, glasses, polymers and composites.

• New electrolyte, cathode and interfacial coating materials for SSBs
• Interfacial stability and conductivity design of solid electrolytes against metal anodes and high-voltage cathodes
• Process-structure-property relationships in the synthesis and scale-up of solid electrolytes and composite electrodes
• Li and Na metal anodes (including initially anode-free configurations) in SSBs
• Advanced characterization using imaging, spectroscopy, diffraction, and In situ/operando techniques
• Materials genome approaches, machine learning, multiscale modeling of materials and devices
• Mechanical stress, deformation and fracture evolution at solid electrode-electrolyte interfaces
