湿法回收废旧锂电池正极材料中有价金属研究进展OA
Research Progress on Hydrometallurgical Recovery of Valuable Metals from Waste Lithium-ion Battery Cathode Materials
锂离子电池(LIBs)凭借其高能量效率、高功率密度、长循环寿命及低自放电率等优点,在新能源和储能领域具有广阔的应用前景.由于锂电池寿命有限,导致产生大量废旧电池.锂电池正极材料中的锂、钴等金属属于战略资源,对其加以回收利用不仅有助于缓解原生资源开采压力,减少环境污染,还能实现金属资源的闭环循环利用.介绍了锂电池组成和回收流程,重点总结了无机酸浸出、有机酸浸出、生物浸出、深共晶溶剂浸出对锂电池正极材料中金属回收的研究进展,旨在为废旧锂电池中有价金属回收提供技术指导.
Lithium-ion batteries(LIBs)are promising for application in new energy and energy storage fields owing to their high energy efficiency,high power density,long cycle life,and low self-discharge rate.However,the limited lifespan of lithium batteries leads to substantial generation of waste batteries.Metals such as lithium and cobalt within their cathode materials belong to strategic resources.Recycling waste lithium batteries not only alleviates pressure on primary resource exploitation and reduces environmental pollution but also enables closed-loop recycling of metallic resources.The composition and the recycling process of lithium batteries are introduced.The research on metals recovery from lithium battery cathode materials through inorganic acid leaching,organic acid leaching,bioleaching,and deep eutectic solvent leaching is summarized.Technical guidance is provided for the recovery of valuable metals from waste lithium batteries.
