Solid State Batteries: Solid‐State Li–Metal Batteries: Challenges and Horizons of Oxide and Sulfide Solid Electrolytes and Their Interfaces (Adv. Energy Mater. 1/2021)

The introduction of new, safe, and reliable solid-electrolyte chemistries and technologies can potentially overcome the challenges facing their liquid counterparts. In article number 2002689, Jennifer L. M. Rupp and co-workers provide a thorough understanding of the major challenges in materials and interfaces, and mitigation strategies associated with all-solid-state Li metal batteries, where either oxides or sulfide-based solid electrolytes are in the spotlight.
