The increasing demand for energy storage devices has motivated the need to find environmentally friendly, high energy density, and cost-effective materials for energy storage and suitable synthesis techniques. In this work, we report a simple and cost-effective chemical route, in which intermediate Ni_1/3Co_1/3Mn_1/3(OH)₂ product was primarily prepared using a simple redox synthesis technique at ambient temperature. Lithiation reactions were then performed at higher temperatures to develop the final layered Li_x(Ni_1/3Co_1/3Mn_1/3)O₂ structure (where x= 1.0 and 1.05). The lithium content was varied in order to analyze the effect of excess lithiation on the structural and electrochemical properties of the layered-type Li(Ni_1/3Co_1/3Mn_1/3)O₂ cathode. The XRD studies clearly confirmed the formation of layered-type structures corresponding to hexagonal α-NaFeO₂ (space group R-3m). The ICP studies confirmed the stoichiometric chemical composition (Li(Ni_0.32Co_0.33Mn_0.31)O₂) of the prepared samples. FE-SEM images revealed that the particle growth occurred when the particles were heated at elevated temperatures of 950°C, and the average particle diameter was around a few micrometers. The electrochemical tests performed versus lithium indicated that competitive specific capacity values were registered for all the prepared cathodes and the capacity retention was impressive on repeated charge/discharge cycling within the potential range of 3.0 – 4.3 V and a current density of 14 mA/g. In particular, the Li(Ni_0.32Co_0.33Mn_0.31)O₂ sample demonstrated the highest capacity retention value (~ 99%) after 50 cycles and better rate performances of 104, 91, 76, and 67 mAh/g at higher current densities of 229, 457, 914, and 1429 mA/g respectively.
