  "description" : "A modified synthesis process was developed based on co-precipitation method followed by spray drying process. In this process, a spherical shaped (Co{sub 1/3}Ni{sub 1/3}Mn{sub 1/3})(OH){sub 2} precursor was synthesized by co-precipitation and pre-heated at 500 C to form a high structural stability spinel (CoNiMn)O{sub 4} to maintain its shape for further processing. The spherical LiNi{sub 1/3}Co{sub 1/3}Mn{sub 1/3}O{sub 2} was then prepared by spray drying process using spherical spinel (CoNiMn)O{sub 4}. LiNi{sub 1/3}Co{sub 1/3}Mn{sub 1/3}O{sub 2} powders were then modified by coating their surface with a uniform and nano-sized layer of ZrO{sub 2}. The ZrO{sub 2}-coated LiNi{sub 1/3}Co{sub 1/3}Mn{sub 1/3}O{sub 2} material exhibited an improved rate capability and cycling stability under a high cut-off voltage of 4.5 V. X-ray diffraction (XRD) measurements revealed that the material had a well-ordered layered structure and Zr was not doped into the LiNi{sub 1/3}Co{sub 1/3}Mn{sub 1/3}O{sub 2}. Electrochemical impedance spectroscopy measurements showed that the coated material has stable cell resistance regardless of cycle number. The interrupt charging/discharging test indicated that the ZrO{sub 2} coating can suppress the polarization effects during the charging and discharging process. From these results, it is believed that the improved cycling performance of ZrO{sub 2}-coated LiNi{sub 1/3}Co{sub 1/3}Mn{sub 1/3}O{sub 2} is attributed to the ability of ZrO{sub 2} layer in preventing direct contact of the active material with the electrolyte resulting in a decrease of electrolyte decomposition reactions.
