摘要：

Actual transference numbers of M+ and X- ion-constituents in Polymer electrolytes have been determined for an amorphous Poly(ethylene oxide)-based Polymer electrolyte containing lithium perchlorate at 120-degrees-C by means of the Hittorf technique. The indicated value of cation transference number for an 8:1 electrolyte (0.06 +/- 0.05) is significantly lower than those found from other experimental techniques, such as NMR and steady-state polarisation, demonstrating the unsuitability of those methods for estimating this parameter. The Hittorf procedure described should be applicable to other polymer electrolytes.
