The Recycling of Spent Lithium-Ion Batteries: a Review of Current Processes and Technologies (2018, background): “Physical recycling processes are usually applied as pretreatments to separate cathode materials from other components such as current collectors and binders so as to reduce impurities and facilitate subsequent recycling processes [38, 39].”
Extraction of lithium from primary and secondary sources by pre-treatment, leaching and separation: A comprehensive review (2014, methodology): “Reductive leaching of the mechanically treated LIBs in 6 (v/v)%H2SO4 and1%H2O2 solution resulted in a relatively lower recovery of metals (~55% Al, 80% Co and 95% Li) (Dorella and Mansur, 2007).”
