ABSTRACT

This study presents an up-to-date review on the methods and technologies applied for the recovery of Co from end-of-life Li-ion batteries. Considering the upcoming world demand for electric vehicles, it has been demonstrated that Co recycling from such batteries is technically feasible and vital in an attempt to provide a global supply of the metal. In this study, a number of recovery methods (including thermal, mechanical, and manual preprocessing, along with pyro- and hydrometallurgical methods) with distinct efficiency levels was described, several of which may be combined and associated between them in order to improve the overall Co separation and recovery performances.

摘要

本研究对从报废锂离子电池中回收钴的方法和技术进行了最新回顾。考虑到即将到来的世界对电动汽车的需求，已经证明从这种电池中回收钴在技术上是可行的，并且对于提供全球金属供应至关重要。在这项研究中，描述了许多具有不同效率水平的回收方法（包括热法、机械法和手动预处理，以及火法和湿法冶金方法），其中几种方法可以组合并在它们之间关联，以提高整体共分离和回收性能。
