CHEMICAL SYNTHESIS OF AlAND CoDOPED $\style{font-family:Arial}{{\mathrm{LiNi}}_6 {\mathrm{Mn}}_2{\mathrm{Fe}}_2{\mathrm O}_2}$ (NMF) CATHODE MATERIAL

Al and Co doped LiNixMnyFezO2 (NMF) was synthesized using sol-gel method. The effect of dopants on the structural stability of LiNixMnyFezO2 (NMF) cathode material was investigated. For this purpose, the powder preparation was carried out using an aqueous solution of the nitrate precursors followed by calcination at 850 °C 5h. The chemical composition of LiNixMnyFezO2 base material was selected as 622 (Ni/Mn/Fe atomic ratio) and were successfully synthesized in layered form. Chemical composition of the obtained powders was determined by Energy dispersive spectroscopy. Scanning electron microscopy was applied to investigate the morphology of the powders. The crystal structure of the samples was analyzed using X-ray diffraction and Rietveld analysis. Average crystallite size from Rietveld refinement was calculated to be between 60-70 nm. Co-doped and Al-doped 622 cathode materials showed [006]/[102] and [108]/[110] doublets, which is the sign of layered structure with hexagonal ordering.

Al VE Co İLAVELİ LiNi6Mn2Fe2O2 (NMF) KATOT MALZEMESİNİN KİMYASAL YOLLA SENTEZLENMESİ

Al ve Co katkılı LiNixMnyFezO2 (NMF) sol-gel yöntemi kullanılarak sentezlenmiştir. Katkıların LiNixMnyFezO2 (NMF) katot malzemelerinin yapısal stabilitesi üzerindeki etkisi araştırılmıştır. Bu amaçla, tozlar, nitrat öncüllerinin sulu bir çözeltisi kullanılarak hazırlanmış ve 850 ° C'de 5 saatte kalsine edilmiştir. LiNixMnyFezO2 sisteminin kimyasal bileşimi 622 (Ni / Mn / Fe atomik oran) olarak seçilmiş başarıyla sentezlenmiştir. Elde edilen tozların kimyasal bileşimi enerji saçılım spektroskopisi ile kontrol edilmiştir. Tozların morfolojisi taramalı elektron mikroskobu kullanılarak incelenmiştir. Numunelerin kristal yapısı, X ışını kırınımı ve Rietveld analizi kullanılarak analiz edilmiş ve ortalama kristal büyüklüğü 60-70 nm arasında hesaplanmıştır. Co katkılı ve Al katkılı 622 katot malzemelerin tabakalı yapıya sahip olduğu [006] / [102] ve [108] / [110] difraksiyon çiftleri ile görülmüştür.
