What is the difference between AC conductivity and DC conductivity? Is AC conductivity = ionic and DC conductivity = electronic?

I am reading papers on batteries and although mostly people have reported ionic conductivity in Scm-1 but some have reported DC conductivity as well I and am confused as to what that is. Any help...

Impedance = electrical conductivity * length L/ area S. So if you know the impedance, the length of the test, the area, you can calculate the electrical conductivity

Hello Lawrence,

with such less information it is not possible to answer your question.

Very roughly, impedance is the complex counterpart of the conductance in an AC system. In an AC system you get frequency dependent measurements with real and imaginary parts. From these plots/measurements you can get your DC conductance (or at least an idea of your DC conductance) and with knowledge about the precise geometry of your sample you can calculate your conductivity.
