摘要
对废旧锂电池正极材料的剥离工艺进行研究,正极材料与铝箔的分离对金属钴和锂的回收有着直接影响。通过实验发现,钴酸锂在碱性溶液中的剥离效果优于在酸性溶液中的剥离效果。在温度为20℃条件下,浓度为3%的氢氧化钠溶液中搅拌,钴酸锂的总剥离率可以达到98.1%。
In this paper,the stripping process of waste anode materials for lithium battery is studied.The separation of anode material and aluminum foil has a direct impact on the recovery of cobalt and lithium.It is found that the stripping effect of lithium cobaltite in alkaline solution is better than that in acid solution.The total stripping rate of lithium cobaltite can reach 98.1%when it is stirred in 3%sodium hydroxide solution at 20℃.
