good afternoon

I am seeking guidance on selecting the appropriate current density for GCD measurements. I am working on supercapacitor electrodes and I fabricated the carbon electrode(working electrode) with an effective area of 1 cm2. My electrode had low mass loading so the unit of current density in GCD should be mA/cm2 for calculated the areal capacitance. Some research has used a current density starting at 0.14 or 0.4 mA/cm².

Thanking in anticipation
