Article Preview

A series of cathode materials for Li-ion battery, spinel LiMn2-xCexO4 (x=0-0.03), were synthesized by the method of solid-state reaction at high temperature. The XRD data showed that all the synthesis samples were pure spinel phase. The results of charge-discharge tests show that LiMn1.98Ce0.02O4 has the highest discharge specific capacity of 119.6 mAh/g, and the discharge specific capacity of the material was 108.5 mAh/g after 50 cycles at room temperature with a retention of 91.0%, and the coulombic coefficient was still high up to 99.8%.
