- Abstract
This article discusses the challenges associated with the interfaces of lithium (Li) anodes and ceramic solid-state electrolytes in lithium-metal batteries. The authors use in-situ Transmission Electron Microscopy (TEM) to study the electro-chemo-mechanical failures at these interfaces and gain insights into the interplay between electrochemical processes and mechanical stresses during battery operation. They observe phenomena such as Li filamental growth and cavitation, Li-electrolyte reactive wetting, and interface de-cohesion. The study also explores how modifications to the ceramic electrolytes can enhance interface stability and extend the lifespan of Li-metal batteries. The findings contribute to our understanding of failure mechanisms in Li-metal batteries and highlight the potential of in-situ TEM techniques for designing more reliable energy storage systems.
