High-Performance Interfaces for Safe Batteries
A self-limiting phase transformation was discovered between a solid electrolyte (SE) and Li-metal using real time, in situ scanning transmission electron microscopy (STEM).
Significance and Impact
This new strategy can be used to design stable and conductive interfaces, leading to safer, high-performance batteries.
