For particle properties, since we assume that the AM particle is a pure, coarse-grained, LFP aggregate, we can retain the same values of Young modulus and Poisson ratio, as our previous model in . For BC particles, we assume they are a granular mixture of three polymers with different material properties in a specific mass ratio, with the addition of carbon nanofibers. We estimate the Young modulus for BC particles 𝐸 𝐵𝐶 using the Halpin-Tsai Equation which reads as In order to keep a reasonable computational cost of the simulations, the most straightforward approach is to use the adjusted values of the particle properties instead of the real values measured in the experiments, especially the Young modulus parameter [ , , ].
