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...
A large amount of spent LiFePO4 (LFP) has been produced in recent years because it is one of the most widely used cathode materials for electric vehicles. The traditional hydrometallurgical and pyrometallurgical recycling methods are doubted because of the economic and environmental benefits; the direct regeneration method is considered a promising way to recycle spent LFP. However, the performance...
