Hydrothermal synthesis of antimony oxychlorides submicron rods as anode materials for lithium-ion batteries and sodium-ion batteries

Antimony oxychlorides submicron rods have been successfully synthesized by a simple and facile hydrothermal reaction, as characterized by a series of physical tests. Antimony oxychlorides material shows outstanding lithium-storage performance, which has a high initial discharge capacity of 1355.6 mAh g(-1) and maintaining a discharge capacity of 402 mAh g(-1) after 100 cycles at a current density of 50 mA g(-1) in the voltage range of 0.01-2.0 V (vs. Li/Li+). Even up to 5000 mA g(-1), the discharge capacity of 485 mAh g(-1) is obtained, indicating an excellent rate capability and a prominent cycle performance. What's more, antimony oxychlorides material also exhibits brilliant cycle property in NIBs at a current density of 50 mA g(-1) in the voltage range of 0.01-2.0 V (vs. Na/Na+). Antimony oxychlorides submicron rods have remarkable rate performance and distinguished cycle capability, indicating that antimony oxychlorides material is one of promising anode materials for both lithium-ion batteries and sodium-ion batteries.
