Sodium-ion batteries (SIBs) are promising candidates for large-scale energy storage. Increasing the density of SIBs demands anode materials with high gravimetric and volumetric capacity. To overcome drawback low conventional nanosized or porous electrode materials, compact heterostructured particles developed in this work improved Na storage capacity by volume, which composed SnO
