Sodium metal is a promising anode material for sodium batteries (SMBs) due to its high theoretical specific capacity and low electrochemical potential. However, practical implementation severely limited by dendrite formation, which causes short circuits safety issues. Here, we introduce separator modification strategy using Ag nanoparticles decorated with two-dimensional diamane on commercial polypropylene (PP) substrate (Ag-diamane/PP) enhance the performance of anodes (SMAs). The synergistic effect between sodiophilic network not only accelerates Na⁺ transport through modified but also reduces interfacial resistance. This dendrite-suppression was systematically validated in situ optical microscopy ex scanning electron microscopy. Symmetric Na||Na cells incorporating Ag-diamane/PP exhibit exceptional cycling stability, maintaining more than 3800 h operation at 2 mA cm−2 1 mAh cm−2. Furthermore, full-cell configuration Na3V2(PO4)3@C cathode, separator, Na delivers reversible 94.35 g−1 stable 270 cycles. work highlights as solution advancing dendrite-free SMBs long-term stability energy density.
