有没有会测离子传导数的朋友?
我查文献 就是下面这个公式,
文献上离子传导数的公式
说是用交流阻抗和直流极化的方法测(交流阻抗还好,但是直流极化就不明白了),但是没有弄明白,望大神们指导…………
下面这个是文献上的解释
The lithium ion transference number was determined by a DC polarization/AC impedance combination method . The initial interfacial resistance (R0) of the cell constructed with symmetrical lithium foils was first determined by electrochemical impedance spectroscopy (EIS) measurement。
A chronoamperometric measurement was then carried out with a potential difference (△E) of 50 mV,and the initial current (I0) was measured. After 1000s the steadystate current (Is) was obtained. The steady-state resistance (Rs) was determined by EIS measurement again after the chronoamperometry measurement.
