摘要
研究开发了一种新的溶胶 凝胶法制备LiMn2O4的技术,运用热分析、红外光谱、X射线衍射、比表面积测定等技术研究了前驱体及产物的结构和形貌特点,探讨了煅烧温度、螯合剂用量对LiMn2O4结构、表面形貌及充放电性能的影响。
A solgel preparation technique of spinel LiMn2O4 was developed. The structural and morphological properties of the precursor and oxide powder were characterized by several techniques such as thermal analysis, infrared spectrum, Xray diffraction (XRD) and specific surface area determination. The effects of sintered temperature and the dosage of chelating agent on the structure, surface morphology and chargedischarge capacity were investigated.
