Understanding Cathode–Electrolyte Interphase Formation in Solid State Li‐Ion Batteries via 4D‐STEM

Advanced Energy Materials
Interphase layers that form at contact points between the solid electrolyte (SE) and cathode active material in solid‐state lithium‐ion batteries (SS‐LIBs) increase cell impedance, but the mechanisms for this interphase formation are poorly understood ...
