中文摘要:
      由于LiFePO4和Li3V2(PO4)3材料的特征相近, 制备方法相类似,提供了一种从废旧LiFePO4和Li3V2(PO4)3混合电池中回收Li、Fe和V,再制备xLiFePO4 -yLi3V2(PO4)3的方法。在空气气氛中600℃热处理1h后,去除粘结剂PVDF使活性物质与集流体分离。调节Li、Fe、V和P摩尔比,球磨、锻烧,配制不同比例的xLiFePO4-yLi3V2(PO4)3(x:y=5:1,7:1,9:1)复合电极材料。表征了其形貌、结构和电化学性能,结果表明,回收制备的复合材料将同时具备LiFePO4和Li3V2(PO4)3两种材料的电化学性能,能显著改善LiFePO4的倍率性能,本论文的研究为废旧锂离子电池资源化回收探索了新的途径,具有良好的应用前景,对于环境保护意义重大,必将产生良好的社会经济效益。

英文摘要:
      Li, Fe and V were reclaimed together and preparedSto xLiFePO4-yLi3V2(PO4)3 materials from spent LiFePO4 and Li3V2(PO4)3 LIBs, for the reason that they have similar characteristics and preparation method. The spent battery materials were roasted under 600 oC for 1 hour in air atmosphere to remove the PVDF binder, then the active materials and aluminum foil collector can be separated effectively. The different proportion of xLiFePO4-yLi3V2(PO4)3(x:y=5:1,7:1,9:1) materials were prepared by roasted products through adjusting the mole ratio of Li, Fe, V and P , ball milling and calcining. The morphology, structure and electrochemical of composite material were performed. The results show that the composite material have the electrochemical properties of LiFePO4 and Li3V2(PO4)3 simultaneously, which can significantly improve the LiFePO4 ratio performance. This dissertation explores a new way for the recycling of spent LIBs. The study is of good application foreground. It is very important for environmental protection, and is believed to bring both economic and social benefits to us.
