Features

  • The pybamm_install_odes command now includes support for macOS systems and can be used to set up SUNDIALS and install the scikits.odes solver on macOS (#3417, #3706)
  • Added support for Python 3.12 (#3531)
  • Added method to get QuickPlot axes by variable (#3596)
  • Added custom experiment terminations (#3596)
  • Mechanical parameters are now a function of stoichiometry and temperature (#3576)
  • Added a new unary operator, EvaluateAt, that evaluates a spatial variable at a given position (#3573)
  • Added a method, insert_reference_electrode, to pybamm.lithium_ion.BaseModel that insert a reference electrode to measure the electrolyte potential at a given position in space and adds new variables that mimic a 3E cell setup. (#3573)
  • Serialisation added so models can be written to/read from JSON (#3397)
  • Added a get_parameter_info method for models and modified "print_parameter_info" functionality to extract all parameters and their type in a tabular and readable format (#3584)
  • Mechanical parameters are now a function of stoichiometry and temperature (#3576)

Bug fixes

  • Fixed a bug that lead to a ShapeError when specifying "Ambient temperature [K]" as an Interpolant with an isothermal model (#3761)
  • Fixed a bug where if the first step(s) in a cycle are skipped then the cycle solution started from the model's initial conditions instead of from the last state of the previous cycle (#3708)
  • Fixed a bug where the lumped thermal model conflates cell volume with electrode volume (#3707)
  • Reverted a change to the coupled degradation example notebook that caused it to be unstable for large numbers of cycles (#3691)
  • Fixed a bug where simulations using the CasADi-based solvers would fail randomly with the half-cell model (#3494)
  • Fixed bug that made identical Experiment steps with different end times crash (#3516)
  • Fixed bug in calculation of theoretical energy that made it very slow (#3506)
  • The irreversible plating model now increments f"{Domain} dead lithium concentration [mol.m-3]", not f"{Domain} lithium plating concentration [mol.m-3]" as it did previously. (#3485)

Optimizations

  • Updated jax and jaxlib to the latest available versions and added Windows (Python 3.9+) support for the Jax solver (#3550)

Breaking changes

  • The parameters GeometricParameters.A_cooling and GeometricParameters.V_cell are now automatically computed from the electrode heights, widths and thicknesses if the "cell geometry" option is "pouch" and from the parameters "Cell cooling surface area [m2]" and "Cell volume [m3]", respectively, otherwise. When using the lumped thermal model we recommend using the "arbitrary" cell geometry and specifying the parameters "Cell cooling surface area [m2]", "Cell volume [m3]" and "Total heat transfer coefficient [W.m-2.K-1]" directly. (#3707)
  • Dropped support for the [jax] extra, i.e., the Jax solver when running on Python 3.8. The Jax solver is now available on Python 3.9 and above (#3550)
