Numerical Design and Manufacturing of Lithium-ion Battery Electrodes using Discrete Element Method (DEM) Modelling

The ever increasing demand for renewable energy worldwide means that developing efficient energy storage techniques are of critical importance. Materials in particulate forms are commonly used in essential energy storage systems, e.g. lithium-ion battery electrodes. In this project, Discrete Element Method (DEM) simulation is used to investigate the calendering process of lithium-ion battery electrodes. By combining DEM, X-ray computed tomography and electrochemical analysis, electrode mechanical and structural properties were investigated. Detailed stress and structural evolutions at microscopic particle scale were analyzed. This work provides a highly promising way to digitalize the next generation battery electrode manufacturing and design.
