All-solid-state batteries have the potential to greatly enhance safety and energy/power density by utilizing sulfide-based solid electrolytes, which have the highest ionic conductivity and good interfacial contact with electrodes. Lithium thioborate materials show promise due to their extremely high lithium-ion conductivity and electrochemical stability. This paper summarizes the research history and milestone discoveries of lithium thioborate solid electrolytes, discusses both glassy and crystalline Li-B-S solid electrolytes, and presents the challenges and potential solutions for future development in this field.
All-solid-state batteries can greatly improve safety and energy/power density, bringing superionic conductors to the research frontier of this field. Among all studied solid electrolytes, sulfides have become the most promising technical system due to their highest ionic conductivity, desirable mechanical ductility, and good interfacial contact with electrodes. Theoretical calculations predicted that lithium thioborate materials may have extremely high lithium-ion conductivity, good electrochemical stability, and thus great application promise. In this paper, the research history of lithium thioborate (Li-B-S) solid electrolytes is summarized and reviewed, with elaborations on milestone discoveries. Furthermore, both glassy and crystalline Li-B-S solid electrolytes are discussed in details, followed by introductions of Li-B-S system from experimental and theoretical perspectives. Moreover, the existing challenges and potential solutions are also proposed for the benign development of this field in the future.
