Graphene@nitrogen doped carbon@ultrafine TiO nanoparticles (G-NC@TiO) 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@TiO composite can deliver an excellent capacity retention of 93% even after 5000 cycles, and a superior rate capability.
通过首次对氧化石墨烯/金属有机框架(MOF)前驱体进行退火处理,获得了具有多孔结构的石墨烯@氮掺杂碳@超细TiO纳米颗粒(G-NC@TiO)。作为钠离子电池(SIB)的负极材料,G-NC@TiO复合材料即使在5000次循环后仍能保持93%的优异容量保持率,以及卓越的倍率性能。
