Hi there,
I am currently trying to calculate the halfcell overpotentials of the positive and negative electrode as well as the total cell overpotential.
Actually the sum of both halfcell overpotentials resp. the sum of their absolute values doesn't equal the total cell overpotential. If I replace "Terminal voltage [V]" with "Surface open-circuit voltage [V]" the sum equals the total overpotential
so there are two questions:
What ist the difference between: "Terminal voltage [V]" and "Surface open-circuit voltage [V]"
Are the three overpotential-calculations above correct?
