GREEN SYNTHESIS OF SPHERICAL-SHAPED Ni1/3Co1/3Mn1/3CO3 PARTICLES

Abstract

In this study, we reported a simple and green manufacturing of a uniform, sphereshaped [Ni1/3Co1/3Mn1/3]CO3 nanoparticles, which can be considered as a precursorfor Li[Ni1/3Co1/3Mn1/3]O2 . Ni-Co-Mn carbonate particle was prepared via threesteps, (1), the mixing metal sulfate salts with Na2CO3 which, formed the primaryprecipitation, (2) the addition of (NH4)2CO3, responsible for the increasingconversion rate, (3) the hydrothermal treatment lead to existing of recrystallizationand spherical shape of [Ni1/3Co1/3Mn1/3]CO3 particles. The morphology andcrystalline structure of the present material is characterized by Energy-dispersiveX-ray Spectroscopy (EDS), Scanning Electron Microscopic (SEM) and X-raydiffraction (XRD). Analysis outcomes indicated that the particle's growthmechanism of spherical composition is depend on a dissolution-recrystallizationprocess of metal salts and (NH4)2CO3 dissociation process. This study opens a greenavenue to prepare cathode materials in the lithium-ion battery application.
