Abstract Recycling spent lithium iron phosphate (LFP) batteries is crucial for resource conservation and environmental sustainability. However, the heterogeneous nature of LFP materials presents challenges universal recycling solutions. This work proposes an oxidation‐reduction process to regenerate cathode materials, reconstructing their lattice structure through high‐energy sanding spray drying. The regenerated exhibits uniform elemental distribution, regular spherical morphology, excellent electrochemical performance. initial capacity 144.9 mAh g −1 at 1C with 98% retention after 400 cycles. Additionally, material maintains 135.4 2C, 97% Density functional theory (DFT) calculations confirm that removing Fe 2+ defects enhances Li + diffusion, improving Compared traditional hydrometallurgical pyrometallurgical methods, low‐cost, less polluting, offers a profit 2.45 $ kg . method enables large‐scale, homogeneous while maintaining high not only provides in‐depth study reconstruction but also novel strategy on industrial scale.
