Long‐Life Regenerated LiFePO ₄ from Spent Cathode by Elevating the d‐Band Center of Fe (Adv. Mater. 5/2023)

Cathode Materials The cycling performance of regenerated LiFePO4 by the direct recycling method is generally not ideal due to the migration of iron (Fe) ions during cycling. In article number 2208034, Zheng Liang, Guangmin Zhou, Hui-Ming Cheng, and co-workers report long-life regenerated LiFePO4 from the spent cathode. Fe–O bonding is strengthened and the migration of Fe ions is suppressed by elevating the d-band center of the Fe. Therefore, excellent cycle performance of LiFePO4 is realized and this strategy provides a guideline for achieving good performance of regenerated LiFePO4.
