초록
The electrochemical properties of cells assembled with the LiNiO2 (LNO) recycled from cathode materialsof waste lithium secondary batteries (Li[Ni,Co,Mn]O2), were evaluated in this study. The leaching, neutralization andsolvent extraction process were applied to produce high-purity NiSO4 solution from waste lithium secondary batteries. High-purity NiO powder was then fabricated by the heat-treatment and mixing of the NiSO4 solution and H2C2O4. Finally, LiNiO2 as a cathode material for lithium ion secondary batteries was synthesized by heat treatment and mixingof the NiO and Li2CO3 powders. We assembled the cells using the LiNiO2 powders and evaluated the electrochemicalproperties. Subsequently, we evaluated the recycling possibility of the cathode materials for waste lithium secondary batteryusing the processes applied in this work.
