Speech Title: Solid-State Batteries : Fundamentals and Challenges
Abstract: Solid-state batteries (SSBs) have attracted enormous attention as one of the critical future technologies due to the probability to realize higher energy density and superior safety performance compared with the state-of-the-art lithium ion batteries. As the key component in SSBs, solid-state electrolytes (SSEs) with non-flammability and good adaptability to lithium metal anodes have attracted extensive attention in recent years. However, there are still intimidating challenges for developing low cost and industrially scalable solid-state batteries with high energy density and stable cycling life for large-scale energy storage and electric vehicle applications. This presentation offers an overview on the scientific challenges, fundamental mechanisms, and specifically focusing on the stability issues of solid-state electrolytes and the associated interfaces with both cathode and anode electrodes. Following the obtained insights, perspectives are given in the end on how to design practically accessible solid-state batteries in the future.
