The layered xLi2MnO3·(1-x)(LiMn1/3Co1/3Ni1/3)O2 (x = 0.15, 0.3, 0.45) as cathode materials in Li-ion batteries were prepared by co-precipitation of hydroxides. The effects of sintering duration, chemical composition and temperature on the structure and electrochemical performance were studied. The results show that the 0.3Li2MnO3·0.7(LiMn1/3Co1/3Ni1/3)O2 material prepared at 800 °C for 20 h has higher crystallization degree and better electrochemical performance. The charge capacity in the first circle was 359.8 mAh·g-1, the discharge capacity was 240.3 mAh·g-1, the discharge efficiency was 66.8% and the capacity retention was also 97.6% after 20 cycles.
