摘要：Spinel LiMn2O4 microspheres were prepared by lithiating MnCO3 solid microspheres and MnO2 hollow microspheres, respectively. Li2CO3 was used as lithium source. The spinel LiMn2O4 microspheres samples annealed at different temperatures were characterized by XRD, SEM, and galvanostatic charge/discharge profile measurement. The LiMn2O4 microspheres show an initial discharge capacity reaches 128 mAh/g at 1 C, more than 120 mAh/g of capacity is retained after 80 cycles and the best cycling stability. These results indicate that the LiMn2O4 microspheres could be a promising cathode material for lithium ion batteries.
