退役三元锂电池回收方法的生命周期评估
摘要:摘要开发了一个生命周期评价框架,分析使用中国工厂实施的传统湿法冶金技术回收镍钴锰(NCM)和镍钴铝(NCA)电池对环境的影响。结果表明,回收NCA电池带来的温室效益类指标要低于NCM电池,但其淡水生态毒性、人类致癌毒性、海洋生态毒性这三个指标却高于NCM电池,因此传统的湿法冶金方法需要被完善。两种电池的回收过程对环境的影响均为负增长,而且在回收最开始的阶段对环境影响最大。研究结果可为动力电池回收企业技术更新提供参考。
Abstract::A life cycle assessment framework was developed to analyze the environmental impacts of recycling nickel-cobalt-manganese (NCM) and nickel-cobalt-aluminum (NCA) batteries using conventional hydrometallurgical technologies implemented in Chinese plants. The results show that the recycling of NCA batteries brings lower indicators of greenhouse benefits than that of NCM batteries, while its three indicators of freshwater eco-toxicity, human carcinogenicity toxicity, and marine eco-toxicity are higher than that of NCM batteries, and therefore the traditional hydrometallurgical method needs to be improved. The environmental impacts of the recycling process of both batteries are negative, and the environmental impacts are greatest at the beginning of the recycling process. The results of this study can provide a reference for power battery recycler to update their technology.
