退役三元锂离子电池正极材料中有价金属的回收与再生研究进展
Research Progress on Recovery and Regeneration of Valuable Metals from Cathode Materials of Spent Ternary Lithium-ion Batteries
摘要
Abstract
The cathode material of spent ternary lithium-ion battery is rich in valuable metals such asLi,Ni,Co and Mn,and efficient separation and recovery of these metals is crucial for environmental protection.The principles,conditions and effects of chemical precipitation,solvent extraction and electrochemical deposition for the separation of dissolved Li,Ni,Co and Mn are evaluated and analyzed.According to the failure mechanism of NCM cathode material,the development status,advantages and disadvantages of direct regeneration strategy of solid-state sintering,hydrothermal method and lithium based eutectic molten salt method,and indirect regeneration strategy of coprecipitation method,sol-gel method and electrochemical method are systematically reviewed.The challenges faced in the separation of valuable metals such as lithium,nickel,cobalt and manganese and the recycling of electrode materials are summarized,and the improvement direction is put forward to provide important guidance for the efficient recycling of valuable metals in the cathode materials of spent ternary lithium-ion batteries.关键词
