摘要：

To improve electrochemical performance and structure stability, Li3PO4 surface modification and single crystallization are applied for Li1.2Mn0.54Ni0.13Co0.13O2 to improve structural stability and upgrade electro-chemical performance. The electrochemical characterization indicates that single crystal cathode material with Li3PO4 surface modification has high cycle stability and superior Li+ diffusion coefficient. Li-ion con-ductor Li3PO4 can supply diffusion channels for Li+ migration and inhibit phase transition. Coating Li3PO4 on Li-rich cathode materials is an effective method to improve the electrochemical performance and structure stability of the materials. (c) 2022 Elsevier B.V. All rights reserved.
