Notes:
Spherical Li[removed info]Ni1/3Mn1/3Co1/3[removed info]O2 precursor powders were synthesized by aerosol plasma pyrolysisusing aqueous solution of metal nitrate. XRD, SEM, TEM and BET analysis were used for determi-nation of the composition, morphology, particle size and surface area. SEM observation showedthat the size of as-prepared particles were about 200 nm. The value of geometrical standarddeviation (σg) calculated from the particle size distribution was 1.20, suggesting that the particlesize distribution was narrow. The crystal phase of Li[removed info]Ni1/3Mn1/3Co1/3[removed info]O2 was resulted in layeredrock salt structure with R3m space group. The rechargeable capacity of Li[removed info]Ni1/3Mn1/3Co1/3[removed info]O2 wasabout 142-175 mAh/g. The discharge capacity of Li[removed info]Ni1/3Mn1/3Co1/3[removed info]O2 decreased with increasingcycle number. However, the cycling stability of Li(Ni1/3Mn1/3Co1/3)O2 powders that aerosol plasmapyrolysis process offered superior performance to ultrasonic spray pyrolysis process
