What is the relationship between electroylte concentration and double layer capacitance?

Question

Even assuming the same potential for the different dilutions, i can't find a relationship anywhere... qualitative is good enough for me.

Answer 1

If you think about it, the capacitance is the ability to store charge, so that leads me to conclude:
1)It is has a positive correlation to the concentration
2)It's limited by the size of the double layer. If you have a small area that the double layer is building up on(small electrode)-it'll reach the maximum and then stop being able to increase capacitance despite concentration much faster than if it's a large electrode.
So, I'm guessing, it is something like, the change in capacitance (not the capacitance itself) due to the change in concentration increases until it reaches a limit imposed by the area of the electrode.
It's just qualitative, but you said you didn't mind.
