초록
In this paper, we successfully synthesized the Na-doped Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode by a general co-precipitation. Weinvestigated the influence of Na doping in terms of structural characteristics and electrochemical performances for practicalusage of lithium-ion batteries. Particularly, the Na-doped Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode shows a significant improvementin cyclability of 72.7 % after 80 cycles with no morphology change, compared to the pristine NCM. Therefore, we can concludethat Na-doped Ni-rich LiNi0.8Co0.1Mn0.1O2 can be considered as an effective strategy for state-of-the-art lithium-ion batteries.
