AB  - In this work, a few-layer MXene is prepared and sprinkled on a commercial 
      polypropylene (PP) separator by a facile spraying method to enhance the 
      electrochemistry of the Ni-rich LiNi(0.8)Co(0.1)Mn(0.1)O(2) (NCM811) cathode. 
      Scanning electron microscope (SEM) and X-ray diffraction (XRD) are used to 
      characterize the morphology and structure of MXene. Fourier transform infrared 
      spectroscopy (FT-IR) and a contact angle tester are used to measure the bond 
      structure and surface wettability PP and MXene/PP separator. The effect of the 
      MXene/PP separator on the electrochemical performance of ternary NCM811 material 
      is tested by an electrochemical workstation. The results show that the 
      two-dimensional MXene material could improve the wettability of the separator to 
      the electrolyte and greatly enhance the electrochemical properties of the NCM811 
      cathode. During 0.5 C current density cycling, the Li/NCM811 cell with MXene/PP 
      separator remains at 166.2 mAh/g after the 100 cycles with ~90.7% retention. The 
      R(ct) of MXene/PP cell is measured to be ~28.0 Omega. Combining all analyses results 
      related to MXene/PP separator, the strategy by spraying the MXene on commercial 
      PP is considered as a simple, convenient, and effective way to improve the 
      electrochemical performance of the Ni-rich NCM811 cathode and it is expected to 
      achieve large-scale in high-performance lithium-ion batteries in the near future.
