NOVELTY - A waste ternary polymer power lithium battery recycling method involves discharging the waste ternary polymer power lithium battery. The battery is disassembled and immersed in a sodium hydroxide solution. A copper collector and a cathode material are destroyed and stripped. The stripped cathode material is treated with acetone solution, followed by performing suction filtering by a suction filtering funnel, followed by drying and sieving. The stripped cathode material is crushed followed by sieving, treating with acetone solution, performing suction, and filtering and drying.    USE - Method for recycling waste ternary polymer power lithium battery.    ADVANTAGE - The method enables recycling waste ternary polymer power lithium battery with high recycling efficiency in an economical, rational, and eco-friendly manner.    DETAILED DESCRIPTION - A waste ternary polymer power lithium battery recycling method involves discharging the waste ternary polymer power lithium battery below 2.75V by utilizing dynamic battery test system. The battery is disassembled to obtain a battery unit piece, followed by immersing in 0.5-2 mol/l sodium hydroxide solution for 1 to 3 hours, where weight ratio of the sodium hydroxide solution and battery unit piece is 1:8-15. A copper collector and a cathode material are destroyed, and treating the unit piece by 2-5 mol/l acetic acid (HAc) at 60-100 degrees C for 0.5-1 hour so as to strip the copper collector from a cathode material, where the weight ratio of the unit piece and acid solution is 1:1-3. The stripped cathode material is treated with acetone solution with solid-liquid ratio of 1:3-8 at 40-70 degrees C for 0.5-2 hours, followed by performing suction filtering on the copper collector by a suction filtering funnel. The copper collector is dried at 100 degrees C, and sieved by a yarn sieve. The stripped cathode material is crushed and sieved 40-160 mesh sieve, followed by treating with acetone solution with a solid-liquid ratio of 1:3-8. A suction filtering process is performed on cathode material by a suction filtering funnel and dried at 100 degrees C to obtain a carbon negative material.
