Negative electrode potential

[aminacoric]

I noticed from the dynamic plot that the negative electrode potential is always 0 during a charge/discharge cycle. (The same goes for when I use the SPMe and DFN models).
Why is the negative electrode potential zero?
Can you simulate the individual electrode potentials differently?

The origin of potential is defined to be 0 V at the negative electrode - current collector interface, that's why the potential of the negative electrode is always close to 0 V. You can instead measure the potential difference between electrode and electrolyte, which would probably give the result you are expecting.

Hi,
as described above, the potential of the negative electrode refers to the negative current collector. This is understandable. My further questions would be:

1. What is the reference for the electrolyte potential?
2. How can I get the anode potential related to Li/Li+ without the explicit use of plating in my model?
   I have read the example
   #https://docs.pybamm.org/en/latest/source/examples/notebooks/models/lithium-plating.html.
   But according to my understanding (I may be wrong), the anode potential related to Li/Li+ should be available even without modeling the plating. If not, could you please explain me why this is so?
   Thank you very much for your support.
