NCM湿法回收
数据集使用建议 使用NCM和LFP电池的生命周期清单(LCI)数据时,用户应考虑到数据代表了截至2018年至2019年的锂离子电池技术状况。此外,电池回收的LCI基于特定中国电池回收商的调查数据,并假设从收集点到回收厂的运输距离为100公里。使用这些数据时应考虑自数据收集期以来可能发生的技术更新和地区实践变化。用户在将数据应用于其他背景或比较研究时,还必须承认评估产品系统的功能单元——电动自行车(EB)行驶的距离。
产品或过程的技术目的 NCM湿法回收工艺用于从废弃的NCM电池中回收前体材料,特别是锂镍钴锰酸盐氧化物(NCM)。这使得可以重新提取有价值的金属用于新电池的生产。此过程与电池生产、回收和材料回收相关的行业尤其相关,特别是对于锂离子电池原料的恢复。

功能单元 The product systems evaluated in this study are EB batteries. The service provided by these batteries is the distance driven; thus, the functional unit in this study is defined as an overall 100-km driving distance of a typical EB driven by a group of batteries (4 × 12 V, 20 Ah). According to the data of EB manufacturers, LFP, and NCM batteries can support a typical EB to travel for approximately 45 km and 50 km with one charge, the calculated lifetime distance is of 36, 000 km, and 30,000 km, respectively.
