Synthesis and characterization of LiNi_0.6Co_0.1Mn_0.3O₂ cathode materials

In this paper, LiNi_0.6Co_0.1Mn_0.3O₂ materials were synthesized via co-precipitation and high temperature solid state reaction. The obtained materials were investigated by powder X-ray diffraction (XRD) technique and scanning electron microscopy (SEM). Then LiNi_0.6Co_0.1Mn_0.3O₂ materials were fabricated into a button cell and the electrochemical properties were investigated. The results show that the discharge capacity of LiNi_0.6Co_0.1Mn_0.3O₂ material increases with the increase of sintering temperature and shows the optimal electrochemical properties at 900 ℃. The initial discharge capacity of the n(Li)/n(Ni+Co+Mn)=1.09 material reaches 143.7mAh/g at 1C rate with lithium dosing of 1.09 at the room temperature, and the specific discharge capacity of the cathode material retains at 141.3 mAh/g with capacity retention ratio of 98.3 % after 50 cycles.
