摘　　要：通过对新能源汽车电池组分的分析,发现废弃电池金属含量大于自然矿场含量,具有较高的回收效益,然后,通过对三种锂离子电池的组成成分进行了分析,认为对于电池的处理过程中先进行预处理,然后进行重新提炼具有非常重要的实际意义。由于我国电池处理产业正处于快速发展期,为了探索电池预处理工艺的效益,提出使用模糊层次法对电池预处理工艺进行研究,并通过从分离效率、环保性能、经济性能和工艺难度四个方面对溶剂溶解法、氢氧化钠(NaOH)溶解法、机械分离法三种电池预处理工艺进行了分析研究。Through the analysis of new energy vehicle battery components.It is found that the metal content of waste battery is higher than that of natural mine,which has higher recovery efficiency.Through the analysis of the composition of three kinds of lithium-ion batteries,it is considered that it is of great practical significance to carry out the pretreatment first and then refining in the process of battery treatment.Due to the rapid development of China's battery treatment industry,in order to explore the benefits of battery pretreatment process,this paper proposes to use the fuzzy AHP to study the battery pretreatment process,and through the separation efficiency,environmental performance,economic performance and process dfficulty four aspects of solvent dissolution method,sodium hydroxide dissolution method,sodium hydroxide(NaOH)dissolution method Three kinds of battery pretreatment processes by mechanical separation were studied.
