| description | Glycine Nitrate Combustion (GNC) method was successfully employed for the synthesis of Li(Ni<sub>1/3</sub>Mn<sub>1/3</sub>Co<sub>1/3</sub>)O<sub>2</sub> with powder characteristics appropriate for the cathode of rechargeable Li-ion batteries (LIBs). The outcome of this study proposed an optimum value of 0.6 for the Glycine: Nitrate ratio to obtain phase pure, well crystalline and rather spherical shaped Li(Ni<sub>1/3</sub>Mn<sub>1/3</sub>Co<sub>1/3</sub>)O<sub>2</sub> micron size secondary particles by the GNC process. These secondary particles were composed of softly agglomerated primary particles of 200 - 300 nm in size. This particle morphology is regarded as a highly favorable for the functioning as a cathode in LIB. The electrical conductivity of Li (Ni<sub>1/3</sub>Mn<sub>1/3</sub>Co<sub>1/3</sub>) O<sub>2</sub>, determined by the dc four-probe technique, revealed the semiconducting nature with conductivity of the order of 10<sup>-7</sup> S cm<sup>-1</sup>, at 25 °C. Lithium ion half-cell constructed with this prepared cathode material showed initial discharge capacity of 187 mAhg<sup>-1</sup> with irreversible capacity of 25 mAhg<sup>-1</sup> at C/5 rate with a cut-off voltage of 2.5 - 4.6 V, at 25 °C. This performance can be attributed to the highly favorable particle morphology obtained by the successful use of GNC process for the powder synthesis. |
