| Popis: | Sodium-ion batteries (SIBs) have attracted lots of significant interests, arising from in regard to the development of developing a low-cost energy storage system for renewable energy. Antimony-based materials with that have high theoretical storage capacities of Na + have become one of the most focused SIB anode materials. Among of which, Sb 2 O 4 has a higher and thus superior Na + storage capacity of 1227 mAh g −1 compared to other antinomy-based materials. In this work, one simple solvothermal process has been developed to prepare Sb 2 O 4 /reduced graphene oxide (Sb 2 O 4 /RGO) composites with a nanostructure of Sb 2 O 4 nanorods anchored on RGO. Sb 2 O 4 /RGO shows an obviously enhanced electrochemical performance with an initial Na + storage capacity of 842 ± 5 mAh g −1 , a rechargeable capacity of 551 ± 5 mAh g −1 at 50 mA g −1 after 100 cycles and an excellent rate performance of 401 ± 5 mAh g −1 at 1 A g −1 . |
