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.

玻璃陶瓷LI_2S-P_2S_2 S_5在室温下具有5×10^-3>的电解质，通过优化母玻璃，结晶条件，玻璃化学稳定性，以硫化物电解质的化学稳定性二进制系统li_2s-p_2s_5。
