Abstract

Using cobalt-free Li1.2Mn0.53Ni0.27O2 (LMNO) cathode material and Acetoacetate ethylene glycol methacrylate (AAEM) as raw materials, in-situ solution polymerization of AAEM was used to form an organic coating layer on the surface of cobalt-free LMNO cathodematerial to improve its cycling stability and interfacial stability. The influence of AAEM on LMNO layered cathode materials were studied using Transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and Electrochemical Impedance Spectroscopy (EIS), etc. Theresults show that the capacity retention rate of the modified sample is as high as 82% after 300 cyclesat 1C cycle within the voltage range of 2-4.7 V, which is much higher than that of the pristine sample (67% after 300 cycles).The refore, the coordination group on the double-site chelating polymer layer can coordinate with the Transition Metal (TM) ion, which enhances the electrode/electrolyte interfacial stability, increases the cycle stability of cathode materials, and improves the electrochemical performance of the material.

Key words： Co-free Li-rich manganese-based layered cathode material; organic coordination polymer; surface coating; electrode/electrolyte interface; cycling stability
