| 摘 要： | 利用无机溶胶-凝胶技术制备了V2O5-(TiO2)x离子存储电极薄膜。采用X射线衍射(XRD)、原子力显微镜(AFM)、Raman光谱、循环伏安法(CV)和紫外-可见光透射光谱分别研究了复合薄膜的微观结构、化学计量、锂离子注入性能以及光学性能。结果表明复合薄膜具有V2O5的层状结构,其c轴方向的结构取向性有所降低;颗粒尺寸和表面粗糙度显著减小;同时TiO2的复合导致薄膜中V2O5的化学计量发生偏移,氧空位数量增多。当x=0.2时,薄膜具有相对较高的离子存储容量及循环稳定性,并且在离子注入/脱出状态均获得相当高的可见光透过性。

| Abstract: | V2O5-(TiO2)x composite ionic storage electrode films were successfully perpared by the modified inorganic sol-gel route.The microstructures and morphologies,stoichiometry,Li+ intercalation and optical properties of the films were investigated by XRD,AFM,raman spretra,cyclic votammetry measurement and UV-Vis transmission spectra,respectively.The results indicated that the films have a layered V2O5 matrix structure,however,the orientation along c-axis decreased with the inhanced content of TiO2.The grain size... |
