Abstract
Manganese oxide particles with nanometre and several micrometre sizes were prepared by spray pyrolysis from aqueous and polymeric spray solutions. The LiMn2O4 particles prepared from Mn2O3 particles obtained from an aqueous solution with a manganese nitrate precursor had micrometre sizes and a spherical shape. On the other hand, the LiMn2O4 particles prepared from nano-sized Mn2O3 particles obtained from polymeric spray solutions had a fine size, a narrow size distribution, and regular morphology irrespective of the type of manganese precursors. The discharge capacities of the LiMn2O4 particles obtained from an aqueous spray solution with a manganese nitrate precursor dropped from 136 to 115 mAh/g by the 25 th cycle at a current density of 0.1 C. On the other hand, the discharge capacities of the LiMn2O4 particles obtained from a polymeric spray solution with a manganese nitrate precursor dropped from 121 to 105 mAh/g.
