The state-of-the-art of modeling techniques applied to battery manufacturing mainly rely on the use of physics-based models (PBMs) and AI/ML. These models allow researchers to study complex phenomena occurring on a wide array of scales . However, for the purpose at hand, this subsection will focus on the simulation of recycling at the micro-and macroscopic scales and will shed light on how computational tools can be used to optimize our ability to both efficiently and sustainably recycle battery materials.
