Abstract Sodium metal anode holds great potential for high energy density sodium batteries. However, its practical utilization is impeded by significant volume change and uncontrolled dendrite growth. To tackle these issues, a three‐dimensional (3D) hierarchical porous sodiophilic reduced graphene oxide/diamane (rGO/diamane) microlattice aerogel constructed direct ink writing (DIW) 3D printing (3DP) method. The molten Na diffused into the rGO/diamane host to form Na@rGO/diamane anode, which can deliver an ultra‐high capacity of 78.60 mAh cm −2 (1090.94 g −1 ). Benefiting from uniform ion distribution homogeneously distributed diamane enabled dendrite‐free deposition morphology, anodes exhibit long cycle‐life over 7200 h at 1 mA with . Furthermore, also enhances long‐term stability elevated operation temperature 60 °C, sustaining prolonged lifespan 400 Notably, when integrated 3 V 2 (PO 4 ) @carbon (NVP@C) cathode full cell delivers sustained longevity, maintaining 2000 cycles retention rate 95.72%.

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.
