Abstract

In this paper the most recent advances in lithium iron phosphate batteries recycling are presented. After discharging operations and safe dismantling and pretreatments, the recovery of materials from the active materials is mainly performed via hydrometallurgical processes. Moreover, a significant number of works are currently being focused on direct regeneration processes. Both approaches are currently applied only at laboratory scale. The main challenges to be faced when dealing with upscaling these technologies (for example mechanic vs manual dismantling, valuable elements recovery strategy vs all-components recovery strategy) are here presented and discussed.

磷酸铁锂电池回收：现状评估

摘要

本文介绍了磷酸铁锂电池回收的最新进展。在排放操作和安全拆除和预处理之后，从活性材料中回收材料主要通过湿法冶金工艺进行。此外，目前大量的工作都集中在直接再生过程上。这两种方法目前仅适用于实验室规模。此处介绍并讨论了在处理升级这些技术（例如机械与手动拆卸、有价值元素恢复策略与所有组件恢复策略）时面临的主要挑战。
