Hello everyone. Why do I get different cell resistances in magnitude and sign (+/-) when measuring in opposite directions by digital multimeter (DMM)?

On checking the resistance of a cell, I am getting a very high negative resistance (-15 M) and low positive resistance when I exchange the DMM terminals (i.e. check cell from opposite electrodes)....

Does the capacities of cathodes reported in literature include binders and carbon conductors?

If the capacities of cathodes reported in literature include binders and carbon conductors, why do we multiply the areal mass of cathode active material and not the total areal mass of cathode...

How can one calculate areal mass or loading of cathode in mg/cm2? Do I need to calculate area of coating on Al current collector?

I know how to calculate areal loading or mass of Li anode (because Li is fabricated commercially as foils with known thicknesses (µm)) as follows 0.1*Density*Thickness where thickness is given...

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...
