中文摘要	國內目前營運中的廢電池回收廠僅處理鋅錳電池與鹼錳電池，回收的廢鋰電池係採境外輸出處理。以往之化學沉澱法應用在新型三元系鋰電池回收時，因鈷、鎳、錳三金屬共沉澱，導致回收金屬資源之純度與價值大減。本計畫先前已完成分離鎳錳鈷之溶劑萃取技術開發，及超音波輔助酸溶與電滲輔助萃取技術研究。為未來可能進一步實廠化之技術與設備需要，第三年以小型模廠探討三元系(LiCo1/3Mn1/3Ni1/3O2)廢二次鋰電池正極材料之串級萃取程序。技術參數包括萃取混合澄清槽模廠設計與組建、前處理除鋁、萃取劑皂化率等。結果顯示，前處理除鋁程序可有效去除98.52%鋁，同時損失3.27%鋰；三元系金屬平均損失則為可接受的1.09%。除鋁後溶液以模廠三級逆流萃取錳，使用70%皂化比萃取液；得純度95.23%錳；同時損失9.23%鋰、5.58%鈷、3.83%鎳。經六級逆流萃取鈷；得純度94.17%鈷；同時損失9.15%鋰、3.98%鎳。前述金屬回收率可經後製程再提高；純度則經洗滌、反萃、電滲萃取、沉澱再提高。本計畫開發之多級逆流萃取程序，亦可適用於其他含混合金屬廢棄物的純化與回收。

摘要	At present, there was only two battery recovery factory in Taiwan which reclaimed mercury from manganese batteries and alkaline zinc-manganese dioxide batteries. The spent lithium-ion batteries are all exported outside the border. When chemical precipitation method was employed to recovery metals from the new type of NCM (LiCo1/3Mn1/3Ni1/3O2) lithium-ion batteries the three metals co-precipitated and produced a low value material. The first-year and second-year projects of this research studied the best parameters of reclaiming technologies of solvent extraction, ultrasonic wave assisted acid dissolution, and electrodialysis assisted solvent extraction employed to recovery the anodic materials from spent lithium-ion battery. The third-year project was focusing on the small scale pilot plant for the continuous counter-current extraction. The technology parameter included design of extraction mixing tank, removal of alumina, saponification ratio of extractants. The results showed that the pre-treatment process removed 98.52% of alumina with a loss of 3.27% of lithium, and 1.09% of nickel, cobalt, manganese, respectively. The three-stage continuous counter-current extraction process with 70% saponification ratio of extractant got a 95.23% purity of manganese with a loss of 9.23% of lithium, 5.58% of cobalt, 3.83% of nickel, respectively. The six-stage continuous counter-current extraction process got a 94.17% purity of cobalt with a loss of 9.15% of lithium, 3.98% of nickel, respectively. The final recovery ratio and purity of materials can be improved by electrowinning or precipitation process. The technologies developed by this research can also be applied to the separation and recovery of other mixed metal waste.

The spent lithium-ion batteries are all exported outside the border. When chemical precipitation method was employed to recovery metals from the new type of NCM (LiCo1/3Mn1/3Ni1/3O2) lithium-ion batteries the three metals co-precipitated and produced a low value material. The first-year and second-year projects of this research studied the best parameters of reclaiming technologies of solvent extraction, ultrasonic wave assisted acid dissolution, and electrodialysis assisted solvent extraction employed to recovery the anodic materials from spent lithium-ion battery. The third-year project was focusing on the small scale pilot plant for the continuous counter-current extraction. The technology parameter included design of extraction mixing tank, removal of alumina, saponification ratio of extractants. The results showed that the pre-treatment process removed 98.52% of alumina with a loss of 3.27% of lithium, and 1.09% of nickel, cobalt, manganese, respectively.
