Issue 573 implement LGM50 #854

brosaplanella · 2020-02-24T12:05:59Z

Description

Addition of the LGM50 parameter set from

Chang-Hui Chen, Ferran Brosa Planella, Kieran O’Regan, Dominika Gastol, W. Dhammika Widanage, and Emma Kendrick. "Development of Experimental Techniques for Parameterization of Multi-scale Lithium-ion Battery Models." Submitted for publication (2020).

Fixes #573

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

New feature (non-breaking change which adds functionality)
Optimization (back-end change that speeds up the code)
Bug fix (non-breaking change which fixes an issue)

Key checklist:

No style issues: $ flake8
All tests pass: $ python run-tests.py --unit
The documentation builds: $ cd docs and then $ make clean; make html

You can run all three at once, using $ python run-tests.py --quick.

Further checks:

Code is commented, particularly in hard-to-understand areas
Tests added that prove fix is effective or that feature works

looks great thanks @ferranbrosa ! just a few minor comments

...input/parameters/lithium-ion/anodes/graphite_Chen2020/graphite_LGM50_diffusivity_Chen2020.py

+      diffusivity is taken to be a constant. The value is taken from [1].
+      References
+      ----------
+      .. [1] Work in progress


is this the paper in the readme? info could be added here if so

...rs/lithium-ion/anodes/graphite_Chen2020/graphite_LGM50_electrolyte_reaction_rate_Chen2020.py

+    Reaction rate for Butler-Volmer reactions between graphite and LiPF6 in EC:DMC.
+    References

...t/parameters/lithium-ion/anodes/graphite_Chen2020/graphite_LGM50_entropic_change_Chen2020.py

+        + (0.0155 / (0.029 * c_n_max)) * ((cosh((sto - 0.105) / 0.029)) ** (-2))
+    )
+
+    return du_dT * 0


you should just be able to return 0*sto (and remove the unnecessary function for du_dT), or alternatively just set this to be zero in the .csv instead of a [function] and it should work too. the latter is probably cleaner

+    "electrolyte": "lipf6_Nyman2008",
+    "experiment": "1C_discharge_from_full_Chen2020",
+}


take a look at the latest master (see PR #818)-- you can add a reference here so people know to cite your paper if they use your parameter set

I talked to @tinosulzer and he said he would do so after the PR is merged.
