Abstract

In this paper, we successfully synthesized the Li3PO4 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode and investigated electrochemical performances and structure morphology for high-energy lithium-ion battery. The Li3PO4 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 shows superior cation mixing and there is no significant change in morphology compared to the pristine NCM. In particular, the Li3PO4 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 exhibits an improved rate capability of 176.5 mAh g-1 at 4.0 C and cyclability of 80.2% (after 80 cycles). Therefore, the Li3PO4 coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode can be deemed as an effective method for next-generation Li-ion batteries


Keywords: Li3PO4-coated Ni-rich layered LiNi0.8Co0.1Mn0.1O2, superior cation mixing, improved electrochemical performances, Li3PO4 coating layer, next-generation Li-ion batteries
