The proper way is to normalize it according to the weight of the electrode in order to get the specific capacitance in F/g units? or should I normalize it according to the geometric area to get it in F/cm^2?
Thanks in advance,
Ori.
from the discharge curve,
Csp= Ixt/Vxm
I= current
t=discharge current
V= voltage
m= mass of material
To answer your original question, my opinion is that researchers should report the values for both F.g-1 and F.cm-2. There are practical applications where one value may be more important than the other. You may have developed a new system that is fantastic for some applications, yet terrible for others. I feel researchers should be as transparent as possible.
The second question you asked is whether you should report the mass of the entire electrode. As an example, if I was using a glassy carbon electrode as a current collector, I would first determine the performance of this. I would then modify the surface with, for example, CNTs. I would then report the performance gain from adding the CNTs compared with the original surface. I do not think you can simply say "probably is not active".
Regardless, provide as many details as possible. There may be practical limitations, such as the fact a heavy/large current collector is required. I personally feel these things should not be overlooked.
