| Abstract Scope |
In addition to intrinsic material properties, electrode microstructures dictate batteries’ actual operational performance. However, because of the complexities of coupled physics and microstructures, most electrode designs proceed by a traditional trial-and-error fashion. In this work, we employ a direct image-based multiphysics electrochemical simulation framework to perform detailed microstructure-level simulations which can be implemented in an unprecedented speed. Yet the results still contain all the details of multiphysics coupled dynamics in the explicitly considered complex microstructures. We use graphite electrodes to demonstrate these high-throughout-type microstructure simulations with the phase field approach to model the phase transitions in individual graphite particles upon lithiation/delithiation. The simulations were performed on a series of automatically modified graphite electrode microstructures to extract the optimal design to enhance the performance of thick electrodes. We expect the presented simulation tool will facilitate battery developers to accelerate their electrode design. |
