Multifunctional Oleylamine Enables Direct Regeneration of Spent Lithium Iron Phosphate Cathodes through Coupled Lattice and Interface Repair
The rapid accumulation of spent lithium iron phosphate batteries has created an urgent need for sustainable and economically viable direct regeneration technologies. Direct regeneration requires restoring lithium stoichiometry, Fe valence, antisite defects, particle morphology, and surface conductivity. Herein, a mul...
