Abstract

Lithium-ion batteries (LIBs) is widely used in every aspect of our life due to its high energy density and long cycle life. However, the large demand of LIBs will also lead to a substantial end-of-life (EOL) batteries which requiring proper treatment. Recycling EOL LIBs not only mitigates the production of hazardrous waste caused by improper disposal, it also can recover the value from strategic materials. A closed-loop recycling process developed in WPI has demonstrated its success in synthesizing different cathode materials with excellent electrochemical performance when compared with a commercially available cathode. In this presentation, we will discuss the various efforts in our team to recover high quality cathode materials from spent lithium ion batteries and determine the impacts of some potential impurities.
