主　　题：Ionic liquid Lithium Selective extraction Spent lithium batteries Recovery 

摘      要：In light of the increasing demand for environmental protection and energy conservation,the recovery of highly valuable metals,such as Li,Co,and Ni,from spent lithium-ion batteries(LIBs)has attracted widespread *** conventional recycling strategies,however,suffer from a lack of lithium recycling,although they display high efficiency in the recovery of Co and *** this work,we report an efficient extraction process of lithium from the spent LIBs by using a functional imidazolium ionic *** extraction efficiency can be reached to 92.5%after a three-stage extraction,while the extraction efficiency of Ni-Co-Mn is less than 4.0%.The new process shows a high selectivity of lithium *** spectroscopy and ultraviolet are utilized to characterize the variations in the functional groups during extraction to reveal that the possible extraction mechanism is cation *** results of this work provide an effective and sustainable strategy of lithium recycling from spent LIBs.
