I'm using Gamry instrument interface 1000 and it obviously only state current
I've tried to calculate the current density (A/g) by simply current divided by the mass of electrode (without includeing nickel foam)
when i looked at all of my GCD analysis trials for i have 3 trials at 0.005A
all of my trials do not have the same current density value
is my formula was wrong or my concept was not accurate?

For current density calculation in GCD analysis, the reference value depends upon the charactristics of material. For current normalization, try to use average mass (excluding mass of nickle foam, mass of binder and mass of conductive agent). It may occur due to callibration issues, so you should check them too. Thank you.
