Surface amorphization provides unprecedented opportunities for altering and tuning material properties. Surface‐amorphized TiO 2 @graphene synthesized using a designed low temperature‐phase transformation technique exhibits significantly improved rate capability compared to well‐crystallized TiO 2 @graphene and bare TiO 2 electrodes. These improvements facilitates lithium‐ion transport in both insertion and extraction processes and enhance electrolyte absorption capability.
