Anode-free lithium metal batteries (AF-LMBs) have emerged as promising next-generation energy storage systems due to their ultrahigh energy density and cost-effectiveness. Nevertheless, their practical implementation faces significant challenges, including non-uniform lithium deposition and unstable solid-electrolyte interphase (SEI) formation on current collectors, resulting in rapid capacity degradation and limited cycle life. In this study, a ferroelectric lead zirconate titanate (PZT) with orderly ferroelectric dipoles coated polyethylene separator was applied as an artificial SEI layer to stabilize anode-free lithium metal battery. The ferroelectric dipoles induced by PZT's noncentrosymmetric crystal structure effectively build an internal electric field, thus not only modulates Li+ flux and mitigates Li+ depletion near the anode side, but also induces robust adsorption affinity with lithium salts, thereby promoting anion accumulation at the Cu current collector interface and facilitating the formation of an anion-rich SEI layer. Experimental characterizations demonstrate that the resulting SEI exhibits uniform nitrogen and fluorine distribution, which significantly improves interfacial charge transfer kinetics and reduces surface diffusion energy barriers. The synergistic effect of SEI modification and Li+ flux regulation enables dendrite-free lithium deposition with enhanced uniformity. Consequently, the assembled half-cells achieve exceptional cycling stability over 500 cycles at 1 mA cm-2 with a high average Coulombic efficiency of 98.4 %. Furthermore, full-cells incorporating LiNi0.6Mn0.2Co0.2O2 cathodes without lithium pre-deposition maintain stable operation for 250 cycles at 1C. This work demonstrates the effectiveness of ferroelectric-induced interfacial engineering in simultaneously optimizing Li+ flux distribution and constructing anion-enriched SEI with homogeneous nitrogen/fluorine dispersion, offering a viable strategy for developing high-performance AF-LMBs with extended cycle life.
