      abstract     = {Rechargeable lithium (Li) metal batteries face challenges
                      in achieving stable cycling due to the instability of the
                      solid electrolyte interphase (SEI). The Li-ion solvation
                      structure and its desolvation process are crucial for the
                      formation of a stable SEI on Li metal anodes and improving
                      Li plating/stripping kinetics. This research introduces an
                      interfacial desolvation coating technique to actively
                      modulate the Li-ion solvation structure at the Li metal
                      interface and regulate the participation of the electrolyte
                      solvent in SEI formation. Through experimental
                      investigations conducted using a carbonate electrolyte with
                      limited compatibility to Li metal, the optimized desolvation
                      coating layer, composed of 12-crown-4 ether-modified silica
                      materials, selectively displaces strongly coordinating
                      solvents while simultaneously enriching weakly coordinating
                      fluorinated solvents at the Li metal/electrolyte interface.
                      This selective desolvation and enrichment effect reduce
                      solvent participation to SEI and thus facilitate the
                      formation of a LiF-dominant SEI with greatly reduced organic
                      species on the Li metal surface, as conclusively verified
                      through various characterization techniques including XPS,
                      quantitative NMR, operando NMR, cryo-TEM, EELS, and EDS. The
                      interfacial desolvation coating technique enables excellent
                      rate cycling stability (i.e., 1C) of the Li metal anode and
                      prolonged cycling life of the Li||LiCoO2 pouch cell in the
                      conventional carbonate electrolyte (E/C 2.6 g/Ah), with
                      $80\%$ capacity retention after 333 cycles.},
