Project Goals and Description:
Reliable and robust energy storage systems play a crucial role in the national transition towards a carbon neutral economy. Lithium-ion batteries (LIBs) have brought a paradigm shift in the field of energy generation and storage, particularly in electric transportation. However, the annual generation of spent LIBs waste is projected to exceed 5 million tons by 2030, with only 5% being recycled worldwide. While existing recycling processes have been implemented industrially, they face significant challenges such as high energy consumption, low metal separation efficiency, limited recyclability, and substantial waste generation. To promote a circular economy and establish a waste-to-resource supply chain, it is imperative to develop efficient and sustainable metallurgical technologies for LIBs recycling.
The objective of this research project is to advance the recycling of spent LIBs through the development of next-generation recycling technologies based on benign leaching and electrodeposition using deep eutectic solvents. Specifically, we develop a closed-loop process that minimizes waste while maximizing metal recovery. The investigation primarily focuses on improving metal recovery, process kinetics, selectivity, product purity, waste generation, and energy costs.
