Spherical Li[Ni1/3Co1/3Mn1/3]O-2 powders were synthesized from LiOH center dot H2O and coprecipitated spherical metal hydroxide, (Ni1/3Mn1/3Co1/3)(OH)(2) and coated with Al(OH)(3). The Al(OH)(3)-coated Li[Ni1/3Co1/3Mn1/3]O-2 showed a capacity retention of 80% at 320 mA g(-1) (2C-rate) based on 20 mA g(-1)(0.1 C-rate), while the pristine Li[Ni1/3Co1/3Mn1/3]O-2 delivered only 45% at the same current density. Also, unlike pristine Li[Ni1/3Co1/3Mn1/3]O-2, the Al(OH)(3)-coated Li[Ni1/3Co1/3Mn1/3]O-2 cathode exhibits excellent rate capability and good thermal stability. (c) 2005 Elsevier Ltd.
