摘　　要：回顾了具有LISICON结构、NASICON结构、钙钛矿型结构的晶态锂离子固体电解质及氧化物、硫化物、氧化物与硫化物混合型玻璃态锂离子固体电解质的研究情况,介绍了锂离子固体电解质薄膜的研究现状。从研究情况来看,无论是晶态还是玻璃态锂离子固体电解质的室温离子电导率都已达到或超过10-3S·cm-1,与有机液态电解质离子电导率不相上下,且合成工艺已大为简化,因此,只要改进固体锂离子蓄电池的设计和制作技术,很可能实现固体锂离子蓄电池的商业化。而对固体锂离子薄膜电池来说,用射频磁控溅射技术制成的Li/xLi2O yP2O4 zPON/LiCoO2薄膜电池具有良好的性能,已基本达到商业化要求。The research of crystalline solidstate electrolytes with LISICON, NASICON, Pervoskite structures and the glassy electrolytes based on oxides, sulfides and the mixture of both for Liion battery are reviewed. The stateof art of thinfilm solidstate electrolyte is also introduced. For the solidstate electrolyte, the conductivity of both crystalline and glassy Liion conductors reach or excess the magnitude of 10-3 S·cm-1 and thus possible to be applied in solidstate Liion battery. The Liion battery with Li/x Li2OyP2O5zPON/LiCoO2 thinfilm, which is fabricated by radio frequency magnetron sputtering, has good performance and meets the requirement of commercialization.
