This symposium aims to stimulate discussion how to accelerate development of solid electrolytes for high energy and stable solid-state batteries (SSBs). The global rise of electric vehicle (EV) market calls for a higher energy battery alternative. SSBs are very promising as they allow for the use of metal anodes and offer greater thermal stability and safety due to the absence of organic liquid components. Despite these conspicuous advantages, SSBs are still at research stage, leaving a substantial gap before practical adoption. The SSB system brings additional constraints due to ‘solid-state’ form of electrolytes, compared to liquid electrolytes in the conventional Li-ion batteries. Thus, the quest of novel solid electrolytes with high Li ion conductivity, wide electrochemical stability window, excellent compatibility with electrodes, and scalable manufacturability is still ongoing. The discussion in this symposium will cover broad research areas of materials design, high-throughput experimentations, automated experimentations, artificial intelligence/machine learning for materials search, and advanced manufacturing of SSBs. Discussion from experts in materials development, characterization, computation, theory, and production will provide an overview of the state-of-the-art technologies for new solid electrolyte discovery, the current status of solid electrolyte development, and critical insights to advance SSB development. In this symposium, all forms of solid electrolytes, including ceramics, glasses, polymers and composites will be considered, along with their integration in cathode and anode components.
