用NaOH定向溶解氧化膜法分离回收废旧镍钴锰三元锂电池中的活性材料
Recovery of Active Materials from Waste NCM Ternary Lithium Batteries by NaOH-directed Dissolution of Oxide Film Method
摘要
Abstract
Recovery of active materials from the cathode materials of waste NCM ternary lithium batteries using NaOH-directed dissolution method of oxide films was investigated.The effects of solid mass to liquid volume ratio,temperature,and NaOH concentration on the recovery rate of active materials were examined.The results indicate that under the conditions of solid mass to liquid volume ratio,of 4 g/10 mL,temperature of 65 ℃,and NaOH concentration of 3 mol/L,the complete separation of the active materials from the aluminum foil can be achieved in just 1 minute.The shape of the recovered aluminum foil is intact,and the recovery rate of the active materials can reach 98.6％.The method can achieve complete and efficient separation of aluminum foil and active materials from the cathode material with PAA-NH4 as the binder,and has certain promotion and application value.关键词
