Imaging The Microstructure Of Lithium And Sodium Metal In Anode-Free Solid-State Batteries Using Electron Backscatter Diffraction In this research, metal growth and dissolution were investigated using in situ electron backscatter diffraction, yielding new insights:

It is possible to tune the electrochemical properties, such as available stripping capacity, by controlling the deposited microstructure, with a preference for small grains in the microstructure

Controlling the microstructure of the current collector or solid electrolyte may not be a successful path to influencing the deposited metal microstructure. Lithium plated on the lithium foil matches the microstructure of neither the solid electrolyte nor the foil

The merging of grains in electrodeposited alkali metals is driven by grain boundary movement. Tailored impurities, such as seed layers or particles, can influence this mobility and be used to modify the microstructure.
