Solution combustion synthesis of the nanocrystalline NCM oxide for lithium-ion battery uses

Abstract

In this study, the NCM cathode with a chemical composition of were synthesized through a solution combustion method. In this method, metal nitrates and urea were used as precursors and fuel, respectively. The powder obtained from combustion were transferred into a alumina crucible and insert to the muffle furnace and calcined at 750 °C for 15 h. The crystallite size of the sample was calculated with sherer equation to be about 41 nm. The prepared cathode were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry analysis (TGA), differential scanning calorimetry (DSC) and battery charge-discharge test. The initial charge and discharge capacities of electrode containing 94% active material at a rate of 0.05 C in voltage window of 2.5–4.3 V at room temperature was obtained 168.03 and 150.01 mAh g−1, respectively.
