Abstract

We demonstrate that mixed-phase anatase–TiO₂(B) nanoparticles can provide an interesting interphase interface with atomic-level contact for achieving more efficient Li ion storage with high capacity and cycle life. A novel lithium storage mode – “interfacial charge storage in allomorphs” (ICSA) – plays an important role in enhancing Li ion storage.
