Long‐Life Regenerated LiFePO₄ from Spent Cathode by Elevating the d‐Band Center of Fe

Advanced Materials, Journal Year: 2022, Volume and Issue: 35(5)

Published: Oct. 27, 2022

A large amount of spent LiFePO4 (LFP) has been produced in recent years because it is one the most widely used cathode materials for electric vehicles. The traditional hydrometallurgical and pyrometallurgical recycling methods are doubted economic environmental benefits; direct regeneration method considered a promising way to recycle LFP. However, performance regenerated LFP by not ideal due migration Fe ions during cycling irreversible phase transition caused sluggish Li+ diffusion. key addressing challenge immobilize atoms lattice improve capability cycling. In this work, using environmentally friendly ethanol, its stability promoted elevating d-band center via construction heterogeneous interface between nitrogen-doped carbon. FeO bonding strengthened suppressed elevated center. diffusion kinetics improved, leading an excellent reversibility transition. Therefore, exhibits ultrastable at high rate 10 C with ≈80% capacity retention after 1000 cycles.
