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.
