Abstract Scope Alkali metals like lithium play a critical role in battery technology owing to their high energy density. Texture formation by grain selection growth of lithium metal during electrochemical processes is a crucial factor affecting power and safety. Developing a framework to understand and control grain growth is a multifaceted challenge. We will present a general thermodynamic theory and phase-field model to study grain selection growth of the electrodeposited alkali metal. The model is validated by Electron Backscatter Diffraction (EBSD) measurements. Our findings highlight the kinetic limitations of solid-state Li metal batteries stemming from pressure-induced surface energy anisotropy. This insight leads to the development of an amorphous LixSi1-x seed layer, improving the critical current density to 5 mA/cm2 at room temperature for anode-free Li solid-state batteries through the control of grain selection growth to form a (101) texture.
