%description
Simulation of the stochastic 3D structure model for the nanoporous
binder-conductive additive phase in battery cathodes introduced in P.
Gräfensteiner, M. Osenberg, A. Hilger, N. Bohn, J. R. Binder, I. Manke, V.
Schmidt, M. Neumann (2024) <doi:10.48550/arXiv.2409.11080>. The model is
developed for a binder-conductive additive phase of consisting of carbon
black, polyvinylidene difluoride binder and graphite particles. For its
stochastic 3D modeling, a three-step procedure based on methods from
stochastic geometry is used. First, the graphite particles are described
by a Boolean model with ellipsoidal grains. Second, the mixture of carbon
black and binder is modeled by an excursion set of a Gaussian random field
in the complement of the graphite particles. Third, large pore regions
within the mixture of carbon black and binder are described by a Boolean
model with spherical grains.
