Research Abstract |
Material adhesion phenomenon with high-speed collision of powders onto a substrate was investigated through the multi-physics simulations such as Smoothed Particle Hydrodynamics method and Molecular Dynamics method. As the results of the visualization, it was clear that the powders after a collision on the substrate were crushed to finer particles of the 10 nm order within a short time of 10 ns, and were promptly recombined by Coulomb force to form the film. We applied this phenomenon to a silicon cathode film formation for rechargeable batteries for next-generation hybrid cars. It demonstrated the excellent characteristics of charge and discharge cycle.
