Method of Separation of Active Material From Current Collectors using Ultrasonication The increasing demand for lithium-ion batteries has strained the supply chain and highlighted the need for efficient recycling methods to recover valuable materials. This thesis explores the application of ultrasonication as a promising preprocessing technique for material removal in battery recycling. Ultrasonication utilises waves to generate microbubbles that induce cavitation near the electrode surface, resulting in shear forces that facilitate material removal. The study investigates various parameters to optimise the efficiency of ultrasonication. Furthermore, the method demonstrates its potential to produce higher-purity materials compared to conventional shredding processes, thereby enhancing the value of recovered materials.
