Clarification on Reproducing Composite Battery Degradation Model in PyBaMM (Bonkile et al. work)

Dear all,

I am attempting to reproduce the composite battery degradation model presented in Bonkile et al. [1]. The paper states that the modeling work has been integrated into the main PyBaMM repository.

However, while trying to implement parts of the model, I encountered several errors related to the required parameters. Additionally, it is unclear whether the full model has indeed been integrated into PyBaMM. Upon investigation, I found a pull request related to Bonkile’s work that has not yet been merged into the main repository (PR #4516). In contrast, other composite battery-related contributions by O’Kane have been merged (PR #4417).

Given the current state of PyBaMM, is it possible to fully reproduce the composite battery degradation model as described in [1]?

I hope I am making sense and thank you so much for the guidance. :))

Best regards,
Dinesh
