Hello Muhammad Sajjad ,

I am a little confused. When you perform your constant-current discharge measurements I presume you define a discharge current in A, mA, uA, etc. for the potentiostat to apply.

You should then pknow the dimensions (m2,cm2,mm2) and mass (g). You can then calculate the current density (e.g., mA.cm2), etc.

I did these measurments in my desired instruments at these current densities my CCD curves is OK and for 0.001, 0.0002 it didn't show the desired curves of the material and for above values the CCD curves is like my materials curves so my question is; the value i used whether it is in A/g, mA/g , uA/g?

At these valuesmy CCD curves are the same what i want but when i reduced the values as show above such as 0.0001, 0.001 it shows liner line but when i reached to these values which i mention above is Ok so which current density is represent?
