Recycling of LiNi1/3Co1/3Mn1/3O2 in waste lithium-ion batteries by N-methyl-pyrrolidone
An easily industrialized method for the synthesis of LiNi1/3Co1/3Mn1/3O2 from waste lithium-ion batteries (LIBs) is developed in this study. The positive electrode-active material is recycled by N-methyl-pyrrolidone (NMP) and calcination without using organic acid to leach metal. The recycling process parameters, including reaction time, reaction temperatures and solid–liquid ratios, are used to optimize the recycling process. The results show that the reaction time of 20 min, the temperature of 60°C and the solid–liquid ratio of 80 g l–1 lead to a recovery rate of 82%. Carbonates are added to the recycled material to adjust the metal ion ratios and the structures to re-synthesize LiNixCoyMnzO2 (LNCMO). The structure of the re-synthesized LNCMO is characterized by X-ray diffraction analysis and scanning electron microscopy. Electrochemical tests suggest that the waste LIBs can be recycled to re-synthesize new cathode materials with good electrochemical performance, which is comparable to the cathode materials prepared with commercial chemicals.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
