Active materials for lithium battery anodes are infiltrated deep into mesoporous monodisperse starburst carbon spheres. The active materials, silicon and iron oxide (Fe 3 O 4 ), deposit deep inside the mesopores yet maintain full access to both the lithium‐ion and electron‐transport networks. Additionally, for the Fe 3 O 4 , charge–discharge hysteresis is reduced.
