Spherical 0.3LiMn2O3•0.7Li(Ni1/3Co1/3Mn1/3)O2 cathode was synthesized by co-precipitation method followed by calcining at various temperatures (700-950 oC). The structures of the samples were investigated by XRD, SEM, BET and electrochemical method. The results showed that the cathode prepared at 700 oC had the highest discharge capacity of 220.8 mAhg-1 and a satisfactory cycling performance in this study. After 25 cycles, its discharge capacity was still retained as high as 199.6 mAhg-1, which is benefited from the special sphercial microsturcture.

The layered LiNi0.4Co0.2Mn0.4O2was synthesized by co-precipitation method using carbonate sodium as precipitant. The microscopic structural features and morphologies of as-prepared cathode materials were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). And then, the charge-discharge measurements were carried out to determine the electrochemical properties in a voltage range of 2.5-4.6 V. The results show that the pH value in the process of co-precipitation reaction plays a greater part on the electrochemical properties than feed rate does. The cathode materials prepared at higher pH value illustrate better electrochemical properties in the voltage range of 2.5-4.6 V, which can be attributed to a less cation mixing in the cathode material as well as the smaller primary particles and the smaller second particles.
