摘　　要：通过磁控溅射法制备全固态锂离子电池阳极V2O5薄膜,对不同条件下制备的V2O5薄膜用原子力扫描显微镜(AFM)、X射线衍射仪(XRD)和X射线光电子能谱仪(XPS)进行测试分析。结果表明,氧气比例高于20%,溅射功率120W,环境压强1.2Pa时,V2O5薄膜在表面形貌、物相和物态方面表现出良好的电化学性能。We prepared V2O5 thin films as cathode materials for all solid lithium-ion batteries by magnetron sputtering in different conditions. Test and analysis were done by atomic force microscopy scanning （AFM）, X-ray diffraction （XRD） and X-ray photoelectron Sub spectroscopy （XPS）.The results showed that when the oxygen is higher than 20%, the sputtering power is 120W and the ambient pressure is 1.2Pa. V2O5 thin film showed good electrochemical performance from surface morphology, phase and state of matter.
