Abstract

Surface amorphization provides unprecedented opportunities for altering and tuning material properties. Surface-amorphized TiO₂@graphene synthesized using a designed low temperature-phase transformation technique exhibits significantly improved rate capability compared to well-crystallized TiO₂@graphene and bare TiO₂ electrodes. These improvements facilitates lithium-ion transport in both insertion and extraction processes and enhance electrolyte absorption capability.
