The use of efficient batteries and battery materials is essential in our daily life. To ensure a best possible battery efficiency, the pre-stages of these materials should be optimized in their morphology. We address multiphase-field simulation studies of particle growth in a diluted solution to optimize the morphology of the pre-stages materials. The used multiphase-field approach consider diffusion driven particle growth for different particle shapes and anisotropies as well as anisotropic mobilities to ensure realistic growth rates. Incorporating DFT data, we can very accurately represent the shape of the particles as well as the growth rates of the individual facets and thus predict the morphological evolution of the precursors.
