According to the TAFEL PLOT curve measured by CHI, I exported to TXT data, and obtained the data of the potential and current, and then calculated the current to the current density through the data in theRigin.For X, the potential is the potential minus the balance potential
Example of a Tafel plot, overpotential η as a function of 10 log i.
