APPARATUS USING COUETTE-TAYLOR VORTICE REACTION EQUIPMENT FOR PREPARING PRECURSOR OF CATHODE MATERIAL FOR LITHIUM SECONDARY BATTERY

摘要

There is provided an apparatus for preparing a cathode active material precursor for a lithium secondary battery, comprising: a Couette-Taylor reactor where a reaction mixture comprising a solution of mixed metal salts and an alkali solution is admixed to be coprecipitated to form a slurry including the cathode active material precursor; a particle separation unit comprising a separation tank connected to the Couette-Taylor reactor through a slurry supply line and a pulverizer for pulverizing the slurry including the cathode active material precursor, wherein the cathode active material precursor is separated and recovered; and a precipitation unit connected to the Couette-Taylor reactor through a waste solution discharge line, wherein a waste solution discharged from the Couette-Taylor reactor is cooled such that an alkali salt is precipitated and removed.
