AB - Sodium-ion batteries (SIBs) are applied for large-scale energy storage systems, yet their energy density remains capped by hard carbon (HC) anodes with modest gravimetric and volumetric capacities. Herein, we report an alloying-carbon strategy that applies microsized Sn particles with microsized HC particles to form thick-film anodes. The optimized Sn-HC composite couples the high capacity and compaction density of Sn with the structural robustness of HC, displaying the gravimetric and volumetric capacities of 583 mAh g<sup>–1</sup> and 1073 mAh cm<sup>–3</sup>, an initial Coulombic efficiency of 90.5%, a capacity retention of ∼89.5% after 1000 cycles at 0.5 A g<sup>–1</sup>, and limited electrode swelling of 33.7%. Coupled with the Na<inf>3</inf>V<inf>2</inf>(PO<inf>4</inf>)<inf>3</inf> cathode, the SIB full cell delivers an energy density of 254 Wh kg<sup>–1</sup> and high-rate capabilities. Such Sn-HC architecture offers a scalable and industrially relevant route to simultaneously increase the gravimetric and volumetric capacities of anodes for SIBs.
