• Despite the great advantages of hollow structures as electrodes for lithium‐ion batteries, one apparent common drawback which is often criticized is their compromised volumetric energy density due to the introduced hollow interior. Here, we design and synthesize bowl‐like SnO2@carbon hollow particles to reduce the excessive hollow interior space while retaining the general advantages of hollow structures. As a result, the tap density can be increased about 30 %. The as‐prepared bowl‐like SnO2@carbon hollow particles with conformal carbon support exhibit excellent lithium storage properties in terms of high capacity, stable cyclability and excellent rate capability. Super Bowl: A bowl‐like hybrid hollow nanostructure of SnO2@carbon is designed and fabricated as an anode material for lithium‐ion batteries. With advantages of the unique architecture, the bowl‐like SnO2@carbon particles are able to deliver a high discharge capacity of 963 mAh g−1 even after 100 cycles at a current density of 0.4 A g−1.
