Glass-ceramic Li_2S-P_2S_5 electrolytes with a high conductivity of over 5×10^<-3>S cm^<-1>at room temperature were prepared by optimizing preparation conditions of mother glasses, crystallization conditions, glass compositions. Chemical stability of sulfide electrolytes under exposure to air atmosphere was evaluated. The electrolyte with 75 mol% Li_2S showed the highest chemical stability in the binary system Li_2S-P_2S_5. Furthermore, the addition of metal oxides as H_2S absorbents was effective in reducing H_2S gas generation from the electrolytes. All-solid-state In / LiCoO_2 cells with the prepared electrolytes operated as secondary batteries with good cyclability.

通过<-3><-1>对母玻璃制备条件、晶化条件、玻璃组成的优化，制备出室温电导率大于5×10^ S cm^2的Li_2S-P_2S_5微晶玻璃电解质。评价了硫化物电解质在暴露于空气气氛下的化学稳定性。在Li_2S-P_2S_5二元体系中，Li_2S含量为75 mol%时，电解质的化学稳定性最高。此外，金属氧化物作为H_2S吸收剂的加入能有效地减少电解液中H_2S气体的产生。用该电解质制备的全固态In / LiCoO_2电池作为二次电池运行，具有良好的循环性能。
