A novel Sn‐graphite dual‐ion battery (DIB) based on sodium‐ion electrolyte is developed, using Sn foil as both anode and current collector. The Sn‐G DIB presents a reversible capacity of 74 mA h g −1 at 2 C rate and keeps stable for 400 cycles with 94% retention, which also delivers a high energy density of 144 W h kg −1 at 150 W kg −1 .
