摘要

直接再生是废磷酸铁锂(S-LFP)的一种有效策略,主要是选择锂源和还原剂。在这里,通过一种热力学上有利的双功能有机锂盐(柠檬酸锂)反应的辅助,成功实现了磷酸铁锂的单步再生。再生 LFP 的结构和成分得到了显著恢复,在 200 次循环后没有降解,显示出卓越的电化学性能(142.7 mA h g-1)。

Direct regeneration of spent LiFePO4 cathode materials assisted with a bifunctional organic lithium salt†

Direct regeneration is an effective strategy of spent lithium iron phosphate (S-LFP), with the principal aspect being the selection of the lithium source and reductant. Here, assisted with a thermodynamically favourable reaction involving a bifunctional organic lithium salt (lithium citrate), the single-step regeneration of S-LFP is successfully achieved. The structure and composition of the regenerated LFP are significantly restored, demonstrating excellent electrochemical performance (142.7 mA h g−1) with no degradation after 200 cycles.
