Abstract Scope |
Efficient, energy-conscious electrode manufacturing requires a deeper understanding of drying dynamics, which are complex due to multi-phase interactions, phase transitions, and disparate time scales. This presentation introduces a novel Smoothed Particle Hydrodynamics (SPH) framework developed to simulate microstructure evolution during battery electrode drying. The framework features mass-changing SPH particles to capture solvent evaporation and models bubbles as single SPH particles to reduce computational demands. Bubble growth, motion, and breakage are efficiently simulated, with sizes determined by local pressure, temperature, gas mobility, and mass conservation. The presentation will detail the numerical strategies for representing multi-phase interactions, the implementation of dynamic particle behaviors, and the validation of drying behavior and microstructure outcomes. By focusing on long-term bubble dynamics and their influence on the final electrode structure, the SPH framework offers a scalable, physics-informed tool for exploring drying mechanisms, guiding process optimization, and supporting the design of high-performance battery electrodes. |
