| 摘 要： | 成功制备了氧缺陷型Sb2O3-x/rGO复合材料.与纯Sb2O3材料相比,Sb2O3-x/rGO复合材料颗粒尺寸大大减小,导电性能得到提高,作为锂离子电池的负极材料,具有更高的可逆能力、更好的循环稳定性和良好的倍率性能.在电流密度为100 mAh·g^-1的情况下,Sb2O3-x/rGO复合材料的初始放电容量可达1336.6 mAh·g^-1.即使经过50次充放电循环后,其充放电容量依然可以保持在405.8 mAh·g^-1.

| Abstract: | Oxygen-defect Sb2O3-x/rGO composites were successfully prepared in this paper.Compared with pure Sb2O3 material,Sb2O3-x/rGO composite material has greatly reduced particle size and improved electrical conductivity.As the anode material of lithium ion battery,it has a higher reversibility,better cycle stability and greater magnification performance.When the current density is 100 mA·g^-1,the initial discharge capacity of Sb2O3-x/rGO composite material can reach 1336.6 mAh·g^-1.Even after 50 charging and discharging cycles,its capacity can still remain at 405.8 mAh·g^-1. |
