Enhancing Lithium-Ion Battery Performance: Microscale Simulation of Silicon Anode Behaviour

As the demand for sustainable energy solutions grows, lithium-ion batteries with silicon anodes present a promising advancement due to their high charge density and capacity compared to conventional graphite anodes. However, a major challenge is their tendency to swell during lithiation, leading to structural degradation and reduced battery lifespan. This project aims to tackle this issue by developing a smart porous silicon anode structure that accommodates volume expansion while maintaining mechanical integrity. Using microscale Representative Volume Element (RVE) simulations, we will study and optimize this structure to enhance battery performance, safety, and longevity. By leveraging a validated multi-physics simulation approach, this study will support industry partners in improving next-generation battery technology.
