Title "Electrode/Electrolyte Interlayers Enabling Solid State Alkali Metal Batteries"

＜Abstract＞
　Solid-state lithium batteries (SSLBs) have been considered as the most promising next-generation energy storage system because they are expected to circumvent safety issues and enhance energy density. The employment of solid electrolytes (SEs) may enable usage of alkali metals, which possess lowest redox potential and a remarkably high theoretical capacity. Most important is the replacement of volatile and flammable liquid electrolytes with SEs, providing a promising opportunity to reduce, if not eliminate, the risk of fire and related safety issues. Finally, the implementation of SEs allows cells with bipolar design. This enables increased energy densities as well as reduced overall cost because of the minimized non-active components, such as current collectors inside the cells, but also packaging and external electric connections. Thereby, ever-growing interests and efforts from both academia and industry have been dedicated to this field.
　Here we describe a new approach involving the use of thin liquid or polymer/liquid interlayers between the electrolyte and electrodes to enable quasi-solid-state cells. Cells employing various positive electrodes coupled with either lithium or sodium metal electrode, offer good cycling performance even in bipolar-stacked configuration.

＜Short biography＞
STEFANO PASSERINI, Ph.D.
Since January 2023, Dr. Stefano Passerini is Distinguished Senior Fellow at Karlsruhe Institute of Technology.  His research focuses on the basic understanding and development of materials for high-energy batteries and supercapacitors, with the goal to create sustainable energy storage systems from environmentally friendly and available materials and processes. He is an internationally recognized pioneer in the field of ionic liquids and the development of sodium-ion batteries. Co-author of about 800 scientific papers (Scopus H-Index: 118; > 50,000 citations), a few book chapters and several international patents, he has been awarded in 2012 the Research Award of the Electrochemical Society Battery Division. Since 2015 he is acting as Editor-in-Chief of Journal of Power Sources. He has been nominated Fellow of the International Society of Electrochemistry (2016) and the Electrochemical Society Inc (2020). Since 2019 he is a member of the Leopoldina German Academy of Science.
