The present invention relates to a pretreatment method for lithium secondary battery recycling, comprising the steps of: physically discharging waste lithium secondary battery packs, and then dismantling same and cutting terminals so as to manufacture waste lithium secondary battery cells, thereby separating out cell terminals and plastics; punching the waste lithium secondary battery cells; putting same into a closed nitrogen shredder and shredding same, and then injecting the shredded products generated thereby into a closed drying furnace so as to heat same while injecting nitrogen, thereby evaporating and drying organic materials so that the evaporated organic materials are recovered; cooling, to room temperature, the dried shredded products; and pulverizing and sorting the dried shredded products. The pretreatment method for a lithium secondary battery recycling injects nitrogen into the closed drying furnace, maintains the temperature inside a closed tube to be constant, and then applies heat to the shredded products so as to effectively evaporate and recover organic materials of the waste batteries, thereby controlling impurities of the waste batteries.
