Abstract Captured by the remarkable environmental/economic value, recycling spent LiFePO 4 has attracted numerous attention. However, restricted diverse failure mechanisms and different particle‐sizes/active‐sites, strategies still suffer from uneven repairing results poor accessibility. For promoting their application in commercial systems, uniform physical‐chemical properties are urgent for regenerated samples. Herein, tailoring oxidation‐reduction manners, homogeneous cathode materials can be prepared, displaying particle size restored lattice. The capacity of as‐optimized samples kept ≈141.5 mAh g −1 at 1.0 C, 137 with a retention 92% after 300 cycles 2.0 C. After Kg‐scale experiments, pouch full‐cell (LFP‐500 vs recovered graphite) delivers ≈4200 capacity, considerable cycling stability (retention 96.83%, 500 loops). Importantly, detailed mechanism oxidation/reduction‐conditions is investigated, especially lattice reconstitution ions‐ diffusion behaviors. Supported kinetic analysis DFT calculations, fascinating LFP‐500 further proved, mainly derived accelerated Li‐diffusion Compared to traditional recovering oxidation/reduction process displays low cost, energy‐consumption, pollution, accompanied large‐scale potential.

Here, we propose a solid electrolyte coating strategy to stabilize the cathode interface and demonstrate benefit of difluoro(oxalate)borate (LiDFOB) as layer on surface Li6PS5Cl (LPSCl) improve performance LCO 4.5 V. 89.3% initial discharge capacity can be retained after 1500 cycles 1C (1C = 150 mA g–1). ASSLBs loading (35.7 mg cm–2) could deliver an areal over 6 mAh cm–2 (167 g–1) 0.1C keep 85% retention 200 0.3C. The investigation improvement mechanism further verifies that situ decomposition LiDFOB would build (electro)chemomechanically stable interface, which not only suppresses interfacial side reactions but also buffers cracking.
