摘要
用0.5Li3PO4-0.5Li2SiO3为靶材,用射频磁控溅射的方法在N2气氛中制备了非晶结构的固态电解质LiSiPON薄膜。N和Si的引入提高了Li2O-P2O5体系的离子电导率,在室温时电解质薄膜的离子电导率为4.83×10-6S/cm。LiSiPON电解质薄膜与Pt的分解压为5.7V左右,是一种很有潜力的应用于全固态薄膜锂离子蓄电池的电解质材料。
Nitrogen-incorporated lithium silicophosphate （LiSiPON） solid state thin film electrolytes, which are amorphous, were fabricated by RF magnetron sputtering from a 0.5 Li3PO4-0,5 Li2SiO3 target in nitrogen reactive plasma. The incorporation of N and Si increases the ionic conductivity of Li2O-P2O5 systems and the ionic conductivity of LiSiPON thin film electrolyte is 4.83×10^-6S/cm at room temperature. The decomposition potential of LiSiPON thin film in contact with Pt is about 5.7 V and it is a promising electrolyte for all- solid-state thin film lithium ion batteries.
