摘要
采用FTO/LTO(LPO)/TaOx/Al复合结构,利用磁控溅射分别制备TaOx,LTO(LixTiyOz),LPO(LixPOy)薄膜,研究了制备工艺对复合薄膜的微结构、离子传输特性的影响.重点探讨了不同退火温度LTO/TaOx,LPO/TaOx复合结构的光电性能和Li^+界面传输行为.结果表明,LTO/TaOx复合结构中,电荷转移电阻在离子传输中起着重要的作用,界面电导率在很大程度上有助于总电导率;LPO/TaOx复合结构随着退火温度的升高,电解质薄膜之间元素扩散现象加剧,总的离子电导率逐渐减小.
The LTO(LixTiyOz)/TaOxand LPO(LixPOy)/TaOxcomposite structure were prepared by magnetron sputtering method.The microstructure and ion transport properties of the composite films were studied.The photoelectric properties and Li+interface transmission behavior of LTO/TaOxand LPO/TaOx composite structures at different annealing temperatures were discussed in detail.The results indicate that in the LTO/TaOxcomposite structure,the charge transfer resistance plays an important role in the ion transport process,and the interface conductivity contributes to the total conductivity,with the increase of annealing temperature,the element diffusion between the electrolyte films becomes more serious,and the total ion conductivity decreases gradually in LPO/TaOxcomposite structure.
