YEŞİL YÖNTEM İLE KÜRESEL Ni1/3Co1/3Mn1/3CO3 PARÇACIKLARIN SENTEZİ

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 precursor for Li[Ni1/3Co1/3Mn1/3]O2 . Ni-Co-Mn carbonate particle was prepared via three steps, (1), the mixing metal sulfate salts with Na2CO3 which, formed the primary precipitation, (2) the addition of (NH4)2CO3, responsible for the increasing conversion rate, (3) the hydrothermal treatment lead to existing of recrystallization and spherical shape of [Ni1/3Co1/3Mn1/3]CO3 particles. The morphology and crystalline structure of the present material is characterized by Energy-dispersive X-ray Spectroscopy (EDS), Scanning Electron Microscopic (SEM) and X-ray diffraction (XRD). Analysis outcomes indicated that the particle's growth mechanism of spherical composition is depend on a dissolution-recrystallization process of metal salts and (NH4)2CO3 dissociation process. This study opens a green avenue to prepare cathode materials in the lithium-ion battery application.
