Separator modification is a promising method for advancing lithium metal anodes; however, achieving homogeneous lithium-ion flux and uniform plating/stripping processes remains challenging. In this work, we introduce novel approach by developing composite separator, termed PVDF-INO, which integrates In(NO3)3 (INO) into polyvinylidene fluoride (PVDF) to create 12 μm thick layer. This addition significantly enhances the interaction between separator electrolyte, creating lithophilic matrix that ensures an even distribution of ions. ion promotes consistent deposition dissolution, resulting in durable, dendrite-free anode. Moreover, PVDF-INO not only affinity with electrolytes but also maintains stable flux, essential reliable safe battery operation. Consequently, it sustains operation over 750 h Li||Li symmetric configuration, low overpotential just 28 mV. Additionally, full cells equipped LiFePO4 cathodes exhibit superior cycling performance, maintaining capacity retention 92.9% after 800 cycles at 1 C. work paves way significant advancements field batteries, offering solution longstanding energy storage challenges.
