💡 Novelty & Significance:
Oleylamine enables one-step solvothermal regeneration of spent LiFePO₄, simultaneously reducing Fe³⁺, repairing lattice defects, suppressing Li-Fe antisite disorder, and stabilizing morphology, then forming an N-doped carbon coating. This multifunctional approach restores capacity (155.2 mAh g⁻¹) and cycling stability, offering a scalable, high-value direct recycling route for spent batteries.
