💡 Novelty & Significance:
This work introduces a microenvironment regulation strategy using dicyandiamide and lithium orotate to synergistically remove surface impurities and reconstruct interfaces during direct regeneration of spent LiFePO₄. It enables efficient relithiation with in situ nitrogen-doped carbon layers, achieving 90.9% capacity retention after 1000 cycles at 5 C, offering a techno-economically viable route for closed-loop battery recycling.
