摘要

鉴于报废电动汽车电池的巨大市场份额，高效再生lifepo4对于可持续管理至关重要。一种能够从不同健康状态的细胞中直接再生废lifepo4的通用方法对于实际实施至关重要。在此，我们开发了一种基于草酸/氢氧化锂的再生方法，可以有效地恢复各种降解状态下的混合废LiFePO₄，在0.2℃时提供159.2 mAh g⁻¹的初始容量，并在200次循环中保持稳定性。

Efficient direct regeneration of spent LiFePO4 from various degradation states for sustainable battery recycling†

Efficient regeneration of spent LiFePO₄ is essential for the sustainable management of end-of-life electric vehicle batteries, given their significant market share. A universal method capable of directly regenerating spent LiFePO₄ from cells with varying states of health is crucial for practical implementation. Herein, we developed an oxalic acid/lithium hydroxide-based regeneration approach that effectively restores mixed spent LiFePO₄, achieving a high specific capacity of 163.1 mA h g⁻¹ at 0.1C.
