Abstract Anode‐free lithium metal batteries (AFLMBs) are promising due to ultrahigh energy density, reduced manufacturing costs, and enhanced safety through active elimination. However, their practical implementation remains challenged by unstable electrode‐electrolyte interfaces the resulting rapid species depletion. Herein, an ultrathin ion‐conducting membrane (ICM) is designed, featuring uniformly distributed rigid benzenesulfonimide anionic groups flexible lithiophilic containing ether oxygen groups. The constrained anions enable exceptional charge separation spatial resistance, boosting lithium‐ion mobility, while integrated lithophilic network directs lateral deposition ionic nanochannels. This ICM layer effectively promotes enrichment of at interface constructs stable anion‐derived solid electrolyte interphases (SEI). Meanwhile, layers with electron‐insulating properties can further prevent side reactions, suppress dendritic Li growth acting as a natural shield, in seamless deposition. Specifically, Li||Cu coin cells achieve 99.82% Coulombic efficiency. AFLMBs assembled ICM‐coated copper foil (ICM Cu) NCM811 deliver density 495 Wh kg −1 80.72% capacity retention after 100 cycles. interphasial chemistry design strategy provides insights into precise interfacial engineering realize high‐performance, high‐safety battery systems facilitates development for applications.

The increasing demand for high-specific-energy lithium batteries has stimulated extensive research on the metal anode owing to its high specific capacity and low electrode potential. However, will irreversibly react with electrolyte during first cycling process, forming an uneven unstable solid interphase (SEI) layer, which results in non-uniform deposition of Li ions thus formation dendrites. This could cause a battery short circuit, resulting safety hazards such as thermal runaway. In addition, continuous rupture repair SEIs repeated charge/discharge processes constantly consume active lithium, leads significant decrease capacity. An effective strategy address these challenges is design construct ideal artificial surface anode. review analyzes summarizes mathematical modeling SEI, functional characteristics different components, finally discusses faced by practical applications future development directions.
