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 SnO2 @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...
