I have to calculate specific capacitance (F/g) from galvanostatic charge discharge. in electrochemical test, one is working electrode, platinum sheet as counter electrode and Ag/AgCl as reference electrode, i.e., three electrode cell system. In literature there are two equations to calculate, which one is correct:
1. DOI: 10.1088/0957-4484/27/44/442001
C=2 i. dt/m. dv
2. DOI: 10.1038/srep44562
C= i. dt/m. dv
Which is correct formula to calculate gravimetric specific capacitance from Galvanostatic charge discharge method?
