回收废旧锂离子电池中有价组分的研究现状

Recovery of valuable components from spent lithium ion batteries

锂离子电池广泛应用于移动电子设备、电动汽车和储能等领域,但由于其使用周期有限、产品更新换代快,导致锂离子电池报废数量与日俱增,由此引发的资源及环境问题日益突出。对废旧锂离子电池实现资源化、无害化处理已成为国内外研究的重点。针对目前废旧锂离子电池回收的主要方法进行总结,并简要对比了各方法及工艺的优缺点,在此基础上提出了对今后回收废旧锂离子电池的建议。

The lithium ion batteries have been widely applied in many fields, such as portable electronics, electric vehicles and energy storage, but also cause more and more prominently environmental issues and resource issues for their limited service life and fast replacement. The efficient recycling and disposal of spent lithium ion batteries has been a focused issue for study at home and abroad. The current main disposal methods of the spent lithium ion were summarized and briefly compared on their advantages and disadvantages, based on these, several suggestions for recycling the spent lithiumion batteries in the future were also given.
