Congratulations to Dr. Zhang Zhuoran of the research group for his paper received by the international authoritative journal "Journal of Energy Chemistry"! The topic of the thesis is "Li4-xSbxSn1-xS4 solid solutions for air-stable solid electrolytes".

Professor Xie Jia’s research team researched and synthesized a new solid electrolyte Li4-xSbxSn1-xS4 (0 <x< 1). Among them, Li3.8Sb0.2Sn0.8S4 has the highest ionic conductivity, 3.5 × 10-4S cm-1, which is 5 times that of Li4SnS4 and 3 orders of magnitude higher than Li3SbS4. The structure of Li3.8Sb0.2Sn0.8S4 was identified by the method of XRD refinement, and its structure was the same as β-Li3PS4 suitable for ion conduction. In addition, the new solid electrolyte exhibits high stability and no hydrogen sulfide release in humid air. Finally, we used Li3.8Sb0.2Sn0.8S4 to achieve high-capacity charging and discharging of LiCoO2/Li4Ti5O12 all-solid-state batteries. This work not only enriches the research of air-stabilized sulfide solid electrolytes, but also provides Li3.8Sb0.2Sn0.8S4 structural templates for the further design of new solid electrolytes.
