초록
In this paper, we successfully synthesized Ti-coated Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode and microstructure and electrochemicalperformances for high-energy lithium-ion battery are investigated. The TiO2-coated LiNi0.8Co0.1Mn0.1O2 delivers excellent cationmixing and there is no big difference in morphology between pristine and TiO2 coated LiNi0.8Co0.1Mn0.1O2. The TiO2-coatedLiNi0.8Co0.1Mn0.1O2 has higher electrochemical performances (initial discharge capacity : 201.3 mAh g-1, rate capability : 90.5%at 4.0 C and cyclability : 79.4% after 100 cycles). It can be explained by the positive role of TiO2 layer on the surface ofLiNi0.8Co0.1Mn0.1O2.
