A relationship between local structure and electrical conductivity of new vanadate glasses was investigated by 57Fe-Mossbauer spectroscopy, X-ray diffractometory(XRD), Fourier transformed infrared spectroscopy(FT-IR) and DC four- and two-probe method. It was revealed that a coin cell containing isothermally annealed 15Li2O-10Fe2O3-5P2O5-70V2O5 glass as a cathodeactive material showed high capacity of 500mAh/g. The higher electrical performance was observed at least 8 cycles. We could successfully develope a new vanadate glass exhibiting the higher electrical performance when it is applied as a cathode active materialof secondary battery.

用~(57)Fe-穆斯堡尔谱、X射线衍射仪、傅里叶变换红外光谱、直流四探针法和双探针法研究了新型钒酸盐玻璃的局域结构与电导率的关系。结果表明，以15Li_2O-10Fe_2O_3-5P_2O_5-70V_2O_5玻璃为阴极活性材料的硬币电池具有500mAh/g的高容量，且至少可循环8次。将其应用于二次电池正极活性材料，可以成功地开发出一种具有较高电性能的新型钒酸盐玻璃。
