摘要
随着新能源汽车的迅猛发展,磷酸铁锂动力电池退役后将产生大量的废旧电池,若不及时处理将会污染环境和浪费金属资源。介绍了近几年来废旧磷酸铁锂电池正极材料回收利用技术进展,包括湿法回收有价金属、废旧磷酸铁锂修复再生和分解再合成磷酸铁锂等,并指出不同回收方法的优势与不足。最后展望了未来废旧磷酸铁锂电池回收技术的发展方向。
With rapid development of new energy vehicles,a large number of waste batteries will be generated after retirement of LiFePO4 power batteries.It will pollute environment and waste metal resources if they are not disposed of in time.Recycling technology progress of spent LiFePO4 cathode materials in recent years was introduced,including hydrometallurgical recovery of valuable metals,repair and regeneration of spent LiFePO4 and decomposition and resynthesis of LiFePO4,etc.Advantages and disadvantages of different recycling methods were pointed out.Development direction of spent LiFePO4 batteries recycling technology was prospected.
