Abstract

Graphene@nitrogen doped carbon@ultrafine TiO₂ nanoparticles (G-NC@TiO₂) with porous structure are obtained through annealing the precursor of graphene oxide/metal–organic frameworks (MOFs) for the first time. As an anode material for sodium ion batteries (SIB), the G-NC@TiO₂ composite can deliver an excellent capacity retention of 93% even after 5000 cycles, and a superior rate capability.
