查询词典 transference number

The ionic conductivity of polymer electrolytes equaled 3.56×10-4 S·cm-1 when the mass fraction of silicotungstate lithium was 8.5% in polymer film. The lithium ions transference number, which was measured by the method of combination of AC impedance with DC polarization, decreased with increase of the mass fraction of Li4SiW12O40 in the porous polymer film.

为了提高聚合物电解质的Li+离子迁移数，人们设法增大阴离子的体积[6~8]使其难以迁移而达到提高Li+离子迁移数的目的，很少应用含有多个Li+离子的锂盐做聚合物电解质的Li+离子载体。

The observed EMF values of oxygen concentration cell coincided withtheoretical values perfectly, indicating that the ceramics were purely oxide-ionicconductors with oxygen ion transference number of 1 under oxygen atmosphere over thewhole temperature range. The electrochemical oxygen permeation rates determined were inaccordance with the theoretical rates calculated from Faradays law, verifying directexperimentally that the oxide-ionic nature of the conduction under oxygen atmosphere. Athigh oxygen partialpressure range pO_2=10~(-5～10~5 Pa, they were almost pure ionicconductors, which was consistent with the result by means of oxygen concentration cell.Whereas at low oxygen partial pressure range pO_2=10~(-5～10~(-15)Pa, the samplesexhibited mixed ionic and electronic conduction.

结果表明，氧浓差电池电动势的实测值与理论值吻合得很好，氧离子迁移数为1，表明该系列样品在该温度下氧气气氛中为纯氧离子导体；氧泵实验结果进一步证实了该系列样品在氧气气氛中为纯氧离子导体；在氧分压pO_2=10~(-5)～10~5 Pa的高氧分压气氛中，电导率与氧分压变化基本无关，表明在该氧分压范围样品为纯离子导体，这与氧浓差电池电动势测定结果相吻合：在低氧分压为10~(-5)～10~(-15) Pa范围，总电导率随氧分压降低而稍有升高，表明在该氧分压范围样品为氧离子与电子的混合导体。
