退役动力锂电池回收工艺研究进展

退役动力锂电池因含有大量的钴、镍、锂、锰等有价金属备受重视,将其进行回收再利用有助于缓解当前国内资源紧张与环境污染的压力.较为全面地阐述了当前国内外动力锂电池回收技术及新工艺,主要包括干法回收工艺、湿法回收工艺及生物浸出回收工艺,并介绍了各工艺环节的研究现状.同时,随着回收工艺研究的不断深入,切实需要更完备的市场回收机制与之相匹配,故寄希望于新工艺在以后回收工业体系应用的更加广泛与成熟,并对动力电池回收再利用领域未来发展做了展望.

Research progress on recovery processes of decommissioned power lithium batteries

The decommissioned power lithium battery has been attracted much attention because it contains a lot of valuable metals such as cobalt, nickel, lithium and manganese. Its recycling and reusing are helpful to reduce the pressure of resource shortage and environmental pollution pressure in China. In this paper, the recovery technologies and new processes of power lithium battery at home and abroad are comprehensively reviewed, mainly including dry recovery process, wet recovery process and biological leaching recovery process, and the research status of each process is introduced. At the same time, with the continuous deepening of research on recycling technology, a more complete market recycling mechanism is really needed to match it. Therefore, we hope that the new processes will be more widely and maturely applied in the recycling industrial system in the future, and will be used in the field of power battery recycling and reuse, which is also prospected.
