Sodium-metal batteries (SMBs) are considered as a compliment to lithium-metal for next-generation high-energy because of their low cost and the abundance sodium (Na). Herein, 3D nanostructured porous carbon particle containing carbon-shell-coated Fe nanoparticles (PC-CFe) is employed highly reversible Na-metal host. PC-CFe has unique hierarchy based on sub-micrometer-sized particles, ordered open channels, evenly distributed carbon-coated (CFe) surface. achieves high reversibility Na plating/stripping processes over 500 cycles with Coulombic efficiency 99.6% at 10 mA cm-2 mAh in Na//Cu asymmetric cells, well 14 400 60 Na//Na symmetric cells. Density functional theory calculations reveal that superior cycling performance stems from stronger adsorption surface CFe, providing initial nucleation sites more favorable deposition. Moreover, full cell host without metal high-loading Na3 V2 (PO4 )3 cathode (10 mg ) maintains capacity 103 g-1 1 even after 100 cycles, demonstrating operation anode-free SMBs.
