The growing demand for electric vehicles (EVs) and the consequent increase in the use of lithium-ion batteries (LIBs) have created the need for efficient and environmentally responsible recycling solutions for spent LIBs. Current recycling technologies, such as pyrometallurgy and hydrometallurgy, involves high energy consumption, material usage, and hazardous waste generation. These challenges highlight the importance of developing innovative strategies to LIB recycling, aligned with sustainable development principles. The goal of this master’s thesis is to evaluate and compare the environmental impacts of three LIB recycling methods: pyrometallurgy, hydrometallurgy, and the AMELIE process, a novel approach proposed by the Università degli Studi di Brescia.
