With　increasing　the　market　share　of　electric　vehicles　(EVs),　the　rechargeable　lithium-ion　batteries　(LIBs)　as　the　critical　energy　power　sources　have　experienced　rapid　growth　in　the　last　decade,　and　the　massive　LIBs　will　be　retired　after　the　service　life　of　EVs.　To　dispose　of　retired　LIBs,　the　comprehensive　recycling　including　echelon　utilization　and　materials　recovery　has　attracted　global　attention　due　to　its　maximization　of　recycling　value.　In　the　development　of　comprehensive　recycling,　extensive　efforts　have　been　devoted　to　resolving　challenges　associated　with　the　pretreatment　processes,　such　as　the　rapid　sorting,　electrolyte　separation,　and　automatic　dismantling.　However,　the　efficiency　and　safety　of　pretreatment　still　need　to　be　improved　to　confront　the　diversity　and　complex　structures　of　massive　retired　LIBs　by　EVs　industry.　Based　on　this,　this　review　will　comprehensively　review　and　analyze　the　current　state　of　technologies　as　well　as　the　technical　challenges　and　perspectives　of　all　key　aspects　of　comprehensive　recycling　and　the　involved　pretreatment,　including　fundamentals　of　state-of-the-art　technologies,　operating　strategies　of　different　applications,　technical　and　environmental　issues　as　well　as　future　research　directions　to　overcome　these　challenges.
