摘要：

Solid electrolytes for all-solid-state lithium batteries are excellent in terms of stability, and their performance has been improved through many studies. However, due to the interfacial reaction with lithium and sold electrolyte, there is a problem that the performance is deteriorated when used for a long time. In this study, the charge/discharge evaluation of more than 50 cycles was conducted and we analyzed the change Ti4+ to Ti3+ in the solid electrolyte using X-ray photoelectron spectroscopy. Finally, it was confirmed that the performance of the LiNbO3-coated solid electrolyte did not decrease even after long-term use.
