Abstract
In this study, the preparation of solid electrolyte materials and their properties were deeply discussed. With the rapid development of new energy technology, solid electrolyte has attracted much attention in the field of lithium ion battery due to its advantages of high safety and high energy density. The purpose of this study is to develop new solid electrolyte materials to improve their ionic conductivity and stability to meet the needs of high-performance batteries. In terms of the research method, we used the sol-gel method combined with the high-temperature sintering process, and successfully prepared a variety of solid electrolyte samples. The crystal structure and micromorphology of the material were analyzed by XRD and SEM. Further, the ionic conductivity, electrochemical window, and cycle stability of the material were evaluated using electrochemical testing techniques. The results show that the prepared solid electrolyte materials have high ionic conductivity and excellent electrochemical properties, among which the ionic conductivity of a new material reaches the order of 10-3 S / cm at room temperature, showing good application prospects.
