Abstract
In this work, novel composition of Nax[Ni0.6Co0.2Mn0.2]O2 (x = 0.5 and 1.0) layered cathode materials were synthesized by using hydroxide co-precipitation and calcined at 850, 900 and 950 °C. We studied the effects of different sodium contents and calcination temperature on the structural and electrochemical properties of this novel cathode material. The change of calcination temperature and sodium content led to different P2-type, P2/P3-type, P2/O3-type, or O3-type structures. The results indicate better electrochemical perfor-mance of the P2-type cathode materials in terms of high discharge capacity and good cycling performance, when compared to P2/P3, P2/O3, and O3-type cathode materials. Na0.5[Ni0.6Co0.2Mn0.2]O2 electrode calcined at 900 °C exhibited a good capacity of 107.15 mAhg-1 and ca-pacity retention over 73 % after 20 cycle. Characterization of this material will help to develop cathode materials for the Na-ion battery cathode.
