Abstract Despite the great advantages of hollow structures as electrodes for lithium‐ion batteries, one apparent common drawback which is often criticized their compromised volumetric energy density due to introduced interior. Here, we design and synthesize bowl‐like SnO 2 @carbon particles reduce excessive interior space while retaining general structures. As a result, tap can be increased about 30 %. The as‐prepared with conformal carbon support exhibit excellent lithium storage properties in terms high capacity, stable cyclability rate capability.
