Paper Title:
Surface Modification of Li (Co1/3Mn1/3Ni1/ 3)O2 Fine Powders Using Aqueous Al2O3 Sol
  Abstract

The surface of Li(Ni1/3Co1/3Mn1/3)O2 was modified with Al2O3 using aqueous alumina sol and the electrochemical properties of the coated oxide were measured and compared with both uncoated and Al-doped one. The alumina coated powder showed 185 mAh/g at first cycle, and 139 mAh/g after 50 cycles in the voltage range of 3.0~4.6 V at 1C rate. The initial discharge capacity of the coated powder was slightly lower than that of the alumina doped one, but the cycle stability of the coated was better than that of the doped.
