How to calculate the mass of the battery?

[tGisbertz]

Hello everyone,

I want to calculate the energy density of the battery for different parameter variations (parameter set OKane2022). For this I obviously need to calculate the battery mass, for which I wanted to do something like that (index f is for bindes):

However there is no electrolyte density (or is there in the parameter set). It seems like a dumb question, but what is the best way to calculate the battery mass in pybamm?

Thanks in advance!

Interesting question, we don't have any of this kind of analysis in PyBaMM but maybe we should. In the meantime, there are a couple of libraries that you could draw inspiration from for doing it yourself https://github.com/mjlacey/cellmodels, https://github.com/ndrewwang/BotB

Generally I think your approach is correct, you just need to look up values for the missing parameters

If it helps, we collected some parameter values in our article O'Regan et al (2022). It is not open access but the preprint here contains the same info.
