| Abstract |
In recent years, the advancement of lithium-ion batteries (LIBs) has grown and become the leading power supplying devices for electric vehicles and portable electronic devices. However, the limited resources and geographical distribution issues of lithium will make LIBs inappropriate to be utilized in large-scale applications such as energy storage systems (ESS) and smart energy grids. As an effort of exploring the breakthroughs, sodium-ion batteries (SIBs) have been attracted because of the high abundance, low-cost, and similar redox reactions of sodium compared to lithium. However, the exploration of high-performance electrode materials is still necessary. Iron difluoride (FeF2) has been considered as one of the most suitable cathode materials for SIBs due to its economic merit, abundance, and high theoretical capacity (about 571 mAh g-1). Unfortunately, FeF2 has often suffered low reversible capacity and cycling stability because of its poor electrical conductivity. In this work, FeF2 nanoparticles wrapped in graphitic carbon (FeF2@GC) was successfully synthesized from Fe-containing metal-organic framework, Fe-MIL-88B. FeF2@GC discharged high initial capacity of about 611.4 mAh g-1 with superior cycling stability in long cycles at a current density of 50 mA g-1.
