Target Audience: 一般
Note (General): Spherical metal (Fe, Al or Mg) doped Li(Ni_<1/3>Mn_<1/3>Co_<1/3>)O_2 precursor powders were synthesized by ultrasonic spray pyrolysis using aqueous solution of metal nitrate. XRD, SEM and BET analysis were used for determination of the composition, morphology, particle size and surface area. SEM observation showed that the size of as-prepared particles were about 0.9 μm with narrow size distribution. The crystal phase of metal (Fe, Al or Mg) doped Li(Ni_<1/3>Mn_<1/3>Co_<1/3>)O_2 vas resulted in layered rock salt structure with R3^^-m space group after calcinations at 1023 K, 10 hrs. No impurity-related peaks are observed from the XRD pattern with various doping metals. Mg and Al doped Li(Ni_<1/3>Co_<1/3>Mn_<l/3>)O_2 showed a very good cycling stability. The Mg substitution for Ni led to the most excellent results. On the other hand, the capacity fading on cycling was observed for Fe(5%, substitution for Mn) and Mg(30%, substitution for Co and Mn) doped Li(Ni_<1/3>Co_<1/3>Mn_<l/3>)O_2.
