Abstract Fascinated by the high value and low pollution, direct recycling of spent LiNi 0.5 Co 0.2 Mn 0.3 O 2 (S‐NCM) has triggered plenty exploring activities. Considering different industry sources, they always display various particle sizes surface traits. Therefore, simple recovery chemical defects hardly meets market demand. Herein, homogenized strategy, containing physical crushing recovering, is introduced to regenerate morphology components S‐NCM, where successfully regenerated samples displayed uniform size stable lattice. Assisted crushing, precursors show a large contacting area with oxygen during reconstruction, accompanied effective repairing internal More significantly, unique manner induces vacancies (OVs) lowering Li/Ni disorder, bringing about enhanced structural stability. Moreover, redox activity improvement binding energy are further revealed theoretical calculations. The as‐optimized considerable capacity 139.6 mAh g −1 remarkable retention 94% at 1.0 C. Even 5.0 C, its could be kept ≈80.8% after 150 loops. Given this, this work expected provide guidance for NCM regenerations, meanwhile offering an in‐depth understanding morphology/lattice reconstruction.

Metal single atoms are widely used to optimize the microstructure of carbon materials improve their ion storage capacity and rate performance, but impact on another key parameter, Coulombic efficiency (CE), is not sufficiently addressed confirmed. Herein, a universal phenomenon reported that carbon-loaded asymmetric sulfur-modified metal-N4 moiety (MN4-S, M = Zn, Fe, Cu, Ni) possesses higher CE than symmetric MN4 moiety, this applicable various matrices, ions (Li+, Na+, K+), charge discharge rates, electrolyte formulations. The MN4-S exhibits larger CEs (0.03-0.46% average CEs, 4.2-28.4% initial CEs) smaller variance compared implying better reversible stability. mechanism driving revealed by ZnN4-S sodium process. coordination promotes rapid diffusion kinetics changing density. Meanwhile, can reduce adsorption energy regulate surface chemical reactivity material increase reversibility storage, thereby achieving
