Temporal Evolution of Lithium Metal Microstructures During Ultra-High-Capacity Stripping/Plating Cycles.

ABSTRACT: The morphology of deposited lithium (Li) is critical to the stability and reversibility of Li-metal batteries (LMBs). While crystallographic features of Li influence deposition morphology, the orientation of Li crystals during electrodeposition and their temporal evolution under varying kinetic and interphasial conditions remain unclear. This study investigates Li microstructures during electrodeposition at ultra-high capacities (up to 12 mAh cm⁻²) and over repeated cycling, using scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). The results show that the microstructural evolution of Li depends on the interplay between interphasial properties and deposition kinetics. A layer-by-layer epitaxial Li growth with a coherent lattice orientation is achieva
