Complex fluid represents which co-exist multi-phase state. For example, anode slurry that are used for manufacturing battery electrode are consist of polymer such as CMC and particles such as carbon black and graphite. Complex fluids are characterized by rheological properties that are intrinsically time dependent. That is, their response is governed by the operative time scales – such as processing time – and this dependence is attributed to the fluid’s internal microstructure. For example, prior studies[1] have documented that battery slurry exhibit two distinct yielding behaviors, commonly attributed to polymer-network interactions and to interparticle interactions among graphite particles, respectively. To support these observations, the microstructural organization – and its evolution under flow – must be resolved. Lattice Boltzmann Method (LBM) is a technique for simulating continuum fluids by discretizing time and space using particle distribution function f, which normalize the probability that microscopic coarse – grained particles exist between lattices. This method combines Newtonian dynamics of solid particles with a discretized Boltzmann equation for fluid phase. In this work, we employ LBM to visualize the influence of solvent on particle dynamics and to quantify the resulting properties.
