Abstract
In this study, we thoroughly investigated the impact of the calendering process on the microstructure of lithium-ion battery electrodes and explored the related fracture behavior and heat transfer characteristics. Through numerical simulations and experimental validation, we systematically analyzed the effects of different calendering parameters on the contact force and heat transfer efficiency between particles within the electrode. The results indicate that by appropriately adjusting the calendering parameters, we can optimize the electrode microstructure, increase the particle compactness, and thereby enhance the electrode's stability and mechanical integrity. These in-depth insights provide a substantial theoretical foundation for the manufacturing and design of lithium-ion batteries, potentially offering strong guidance for the development and improvement of future battery technologies.
