The Study of Synthesis Parameters of Synthesis Ni-Rich of LiNi_(0.75)Mn_(0.15)Co_(0.10)O_2 Powder by Co-Precipitation Method

摘要

Lithium Nickel Manganese Cobalt Oxide (LiNi_(0.75)Mn_(0.15)Co_(0.10)O_(2): NMC) is become interested materials for lithium battery applications due to high specific energy and low cost. The pure phase and well-ordered layered structure has been synthesized by co-precipitation method. In this study, the Nickel-rich LiNi_(0.75)Mn_(0.15)Co_(0.10)O_(2 )positive electrode powder was prepared using co-precipitation method. The influence of synthesis parameters such as calcination temperature, time and amount of water for rinse a NaOH and NH_(4)OH were studied. Then, phase formation and structure were studied by X-ray Powder Diffraction (XRD). The morphological changes is also confirmed by scanning electron microscope (SEM). A checking weight loss by thermo gravimetric Analysis (TGA). Finally, the optimum parameter to prepare highest pure NMC powder are rinse suddenly until pH 7 and calcination only single1 step.
