Add example of lithium plating for composite electrodes #4273

Open brosaplanella opened 4 months ago

brosaplanella commented 4 months ago

When writing the release notes I realised there is no example of plating for composite electrodes. This is tricky, especially as additional parameters are required. Having such an example would be very useful.

@DrSOKane, if you have the time to write it that would be great, but otherwise could you post here a source for the parameter values in case someone wants to pick up this issue?

@brosaplanella @DrSOKane

I noticed that while the lithium plating model for composite electrodes is implemented, the chen2020_composite parameter set does not currently include the plating parameters. Would it be helpful to copy the plating parameters from OKane2022 to chen2020_composite and use the same parameter values for both the primary and secondary phases?

If that sounds reasonable, I could also write a small example notebook demonstrating degradation (SEI and plating) in composite electrodes. Let me know your thoughts!

Yes, that sounds good to me. Include a comment in the file stating that the parameters are pulled from another paper (i.e. not provided in the Chen2020 paper).

Hi Ferran/Asher, I remember looking into this a while back and finding it very difficult to find papers where this had been done! I did find one, but as usual some parameters were missing.
