dc.description.abstract | Multi-shell structured binary transition metal oxide powders with a Ni/Co mole ratio of 1:2 are prepared by a simple spray drying process. Precursor powder particles prepared by spray drying from a spray solution of citric acid and ethylene glycol have completely spherical shape, fine size, and a narrow size distribution. The precursor powders turn into multi-shell powders after a post heat-treatment at temperatures between 250 and 800 degrees C. The multi-shell structured powders are formed by repeated combustion and contraction processes. The multi-shell powders have mixed crystal structures of Ni1-xCO2O4-x and NiO phases regardless of the post-treatment temperature. The reversible capacities of the powders post-treated at 250, 400, 600, and 800 degrees C after 100 cycles are 584, 913, 808, and 481 mA hg(-1), respectively. The low charge transfer resistance and high lithium ion diffusion rate of the multi-shell powders post-treated at 400 degrees C with optimum grain size result in superior electrochemical properties even at high current densities.
