英文摘要：

Solid electrolytes have been widely studied as one of the functional materials in recent years. This paper mainly reviewed thenewest research advances of cation conducting solid electrolytes with four valence states, especially those electrolytes conducting tri- andtetravalent ions. The application of the cation conductors in electrochemical gas sensors was also introduced briefly. At the same time, thefacing challenges and the future prospect of solid electrolytes was discussed.
