Solid and hollow microspheres of LiMn2O4 have been synthesized by lithiating MnCO3 solid microspheres and MnO2 hollow microspheres, respectively. The LiMn2O4 solid microspheres and hollow microspheres had a similar size of about 1.5 μm, and the shell thickness of the hollow microspheres was only 100 nm. When used as a cathode material in lithium ion batteries, the hollow microspheres exhibited better rate capability than the solid microspheres. However, the tap density of the LiMn2O4 solid microspheres (1.0 g/cm3) was about four times that of the hollow microspheres (0.27 g/cm3). The results show that controlling the particle size of LiMn2O4 is very important in terms of its practical application as a cathode material, and LiMn2O4 with moderate particle size may afford acceptable values of both rate capability and tap density.
