摘要 :

While the battery research community has been actively searching for high-performance electrode materials, the importance of electrode architecture is often overlooked. In fact, a battery’s operational performance is dictated by electrode microstructures. However, computational studies at microstructure level are poorly embraced. In this talk, we will introduce an image-based numerical method that allows a facile implementation for electrochemical simulations of multiphysics processes in explicitly considered electrode complex microstructures. We will use simulations to unravel the complicated interactions between graphite and hard carbon particles in hybrid anodes, and how that affects the their cycling behavior. Next, thanks to the capability of rapidly implementing direct voxel-based simulations, we will demonstrate a high-throughput framework of autonomous high fidelity microstructure electrochemical simulations to screen optimal secondary structures, e.g., tunnels, for high-rate charge of thick electrodes. As we are open sourcing this simulation framework, we believe this tool is greatly useful for battery developers and materials scientists.
