Summary: | Li-Ni-Mn-O cathode powders with various ratios of nickel and manganese components were prepared by ultrasonic spray pyrolysis from polymeric precursor solutions. The precursor powders were several micron in size, had a spherical shape and hollow morphology irrespective of the ratios of nickel and manganese components. The morphology of the post-treated Li-Ni-Mn-O cathode powders were affected by the ratios of nickel and manganese components. The LiMn1.5Ni0.5O4 and LiNi0.5Mn0.5O2 cathode powders were several micron in size, had a hollow and spherical morphology. However the LiMn2O4 and LiNi0.75Mn0.25O2 cathode powders had a fine size and regular morphology. The mean sizes of the LiMn2O4 and LiNi0.75Mn0.25O2 cathode powders were 1.2 and 0.26 micron, respectively. The initial discharge capacities of the prepared Li-Ni-Mn-O cathode powders changed from 120 to 206 mAh/g according to the ratios of nickel and manganese components. 14 refs. |
