AB  - LiNi(x)Co(y)Mn(1-x-y)O(2) (x >/= 0.5) layered oxide materials are generally 
      considered as one of the most prospective candidates for lithium-ion battery 
      (LIBs) cathodes due to their high specific capacity and working voltage. However, 
      surface impurity species substantially degrade the electrochemical performance of 
      LIBs. Herein, surface reconstruction from layered structure to disordered layer 
      and rock-salt coherent region together with a uniform Li(2)CO(3)-dominant coating 
      layer is first in situ constructed on the single-crystal 
      LiNi(0.5)Co(0.2)Mn(0.3)O(2) (NCM) material by a simple water treatment procedure. 
      The unique surface structure is elucidated by Ar-sputtering-assisted X-ray 
      photoelectron spectroscopy (XPS) and transmission electron microscopy (spherical 
      aberration-corrected-scanning transmission electron microscopy (STEM), 
      high-resolution transmission electron microscopy (HRTEM), and TEM). Meanwhile, 
      neutron powder diffraction (NPD) indicates that the antisite defect concentration 
      is mitigated in the treated materials. The modified samples display superior 
      cycle stability with a capacity retention of up to 87.5% at 1C after 300 cycles, 
      a high rate capacity of 151 mAh g(-1) at 5C, an elevated temperature (45  degrees C) 
      cycling property with 80% capacity retention (4.5 V), and improved full-cell 
      performance with 91% after 250 cycles at 1C. Importantly, postmortem examination 
      on the cycled cathodes by time-of-flight secondary-ion mass spectroscopy 
      (TOF-SIMS), XPS, TEM, and X-ray diffractometer (XRD) pattern further demonstrate 
      that these results are mainly attributed to the thin cathode electrolyte 
      interface (CEI) film and low solubility of transition-metal ions. Therefore, this 
      expedition provides an opportunity to construct an effective armor for the 
      interface compatibility and stability of LIBs.
