1.Glass ceramic materials with various compositions in the system Li_2S-P_2S_5 were prepared by mechanical milling of starting materials and subsequent heat treatment. The 70Li_2S-30P_2S_5 glass-ceramic obtained by crystallization of mechanically milled glass showed a higher ambient-temperature conductivity of 2.2x10^<-3> Scm^<-1>. The enhancement of conductivity was due to the formation of the new, highly conductive, metastable crystalline phase. The main structural units of the crystal were the P_2S_7^<4-> ions.2.The Li_2S-P-S glasses were prepared by mechanical milling from the mixture of Li_2S and elemental phosphorus and sulfur. The Li_2S-P-S glass-ceramics contained mainly PS_4^<3-> ions with a small amount of S-S bonds, and the homo bonds present in the corresponding glasses almost disappeared by the heat treatment of the glasses.3.The all-solid-state cells with the combination of the SnS-P_2S_5 glassy electrode and the Li_2S-P_2S_5 glass-ceramic electrolyte were constructed. The cell using the 80SnS - 20P_2S_5 glass as an anode worked as a secondary battery, which was a first step of glassy monolithic cells with a common glass network.4.All-solid-state cells using cathode materials consisting of sulfur and CuS were successfully prepared and exhibited excellent cycling performance at room temperature.5.The effects of conductive additives in composite positive electrodes on charge-discharge behaviors of all-solid-state In/LiCoO_2 cell with Li_2S-P_2S_5 glass-ceramic electrolytes were investigated. Under relatively high current densities, the cell with VGCF kept larger discharge capacities during 50 cycles compared with the cells with other conductive additives like AB.

1.通过机械铣削的起始材料和随后的热处理制备了系统中具有各种组合物的玻璃陶瓷材料。通过机械铣削玻璃结晶获得的70LI_2S-30P_2S_2玻璃陶瓷显示出较高的环境温度电导率为2.2x10^<-3> SCM^<-1>。电导率的增强是由于形成了新型，高度导电，亚稳态的结晶相。晶体的主要结构单元是P_2S_7^<4->离子。2。LI_2S-P-S玻璃是通过从LI_2S和元素磷和硫的混合物中的机械铣削制备的。 LI_2S-P-S玻璃陶瓷主要包含具有少量S-S键的PS_4^<3->离子，相应眼镜中存在的同金键几乎通过玻璃杯的热处理消失了。3。All-Solid-solid--结合了SNS-P_2S_5玻璃电极和LI_2S-P_2S_5玻璃陶瓷电解质的状态细胞。使用80sns-20p_2s_5玻璃作为阳极作为二次电池的电池，这是具有公共玻璃网络的玻璃状单片细胞的第一步。4。使用硫和CUS组成的阴极材料的所有固相细胞都是成功的。在室温下制备并表现出出色的循环性能。5。复合阳性电极中导电添加剂在/li_2s-p_2s_2s_5玻璃陶瓷电解质中的全溶液中的电荷释放行为的影响。在相对较高的电流密度下，与其他导电添加剂（如AB）相比，具有VGCF的细胞在50个周期期间保持了更大的排放能力。
