Owing to continuing global use of lithium-ion batteries (LIBs), in particular in electric vehicles (EVs), there is a need for sustainable recycling of spent LIBs. Deep eutectic solvents (DESs) are reported as “green solvents” for low-cost and sustainable recycling. However, the lack of understanding of the coordination mechanisms between DESs and transition metals (Ni, Mn and Co) and Li makes selective separation of transition metals with similar physicochemical properties practically difficult. Here, it is found that the transition metals and Li have a different stable coordination structure with the different anions in DES during leaching. Further, based on the different solubility of these coordination structures in anti-solvent (acetone), a leaching and separation process system is designed, which enables high selective recovery of transition metals and Li from spent cathode LiNi1/3Co1/3Mn1/3O2 (NCM111), with recovery of acetone. Recovery of spent LiCoO2 (LCO) cathode is also e

LAWRENCE – Eight University of Kansas graduate students from the Lawrence campus and five graduate students from the KU Medical Center are putting their groundbreaking research on public display starting Feb. 18.
KU students will join graduate students from Emporia State University, Fort Hays State University, Kansas State University, Pittsburg State University and Wichita State University at the Capitol Graduate Research Summit. This year’s event will take place virtually, instead of in the Kansas Statehouse. The graduate students selected to participate represent a wide range of research interests, including physical and natural sciences, medicine and pharmacy, engineering and education. Each institution will provide a $500 award to one student in their institution. BioKansas will provide recognition to six students selected among all the institutions.
