Abstract

Active materials for lithium battery anodes are infiltrated deep into mesoporous monodisperse starburst carbon spheres. The active materials, silicon and iron oxide (Fe3O4), deposit deep inside the mesopores yet maintain full access to both the lithium-ion and electron-transport networks. Additionally, for the Fe3O4, charge-discharge hysteresis is reduced.
