Abstract

Antimony oxychloride (Sb8O11Cl2) microrods with the diameter of about 100 nm are synthesized by a facial solvothermal reaction. And the material of Sb8O11Cl2 is applied as an anode material for sodium-ion batteries for the first time. It can deliver 723.4, 500.6, and 425.5 mA h g−1 after 20 cycles under current densities of 10, 30, and 50 mA g−1, respectively. Besides, the rate performance is also surprising (specific capacities of 517.4, 411.6, 247.8, and 191.2 mA h g−1 are achieved at the current densities of 30, 50, 100, and 200 mA g−1, respectively). Furthermore, the Sb8O11Cl2 electrode is of two very appropriate discharge plateaus (0.4 and 1.3 V) during sodiation/desodiation process, which is very critical for the long-term development of the sodium-ion batteries. In this work, a novel electrode material is presented, and it will encourage more researchers to explore Sb8O11Cl2 deeply due to its outstanding capacity and reversible performance.
