All-solid-state Li batteries (ASSLiBs) that use solid-state electrolytes (SSEs) to replace liquid organic electrolytes are considered as promising next-generation energy storage devices because of their wide electrochemical potential windows, high safety, and high energy density. Therefore, ASSLiBs have attracted a lot of attention in recent years. In this review, we focus on the main challenges on the synthesis and the electrochemical properties of the SSEs including (i) crystal structures and modification of kinetics of Li-ion migration through doping technology, (ii) synthesis technologies and its effect on the electrochemical performances of the SSEs, and (iii) ambient condition stability and degration of SSEs. Finally, perspectives of future researches on the SSEs are presented.
