摘要
以类球形的Ni_(0.65)Co_(0.1)Mn_(0.25)(OH)_(2)前驱体为研究对象,系统地研究了处理温度对该前驱体的比表面积、形貌、粒径、金属含量等理化指标的影响规律。通过X射线衍射、热重、X射线光电子能谱等检测手段揭示了高温处理过程中前驱体物相演变行为、热稳定性以及过渡金属元素的价态变化规律。
The effect of treatment temperature on the specific surface area,morphology,particle size and metal con-tent of spherical Ni_(0.65)Co_(0.1)Mn_(0.25)(OH)_(2) precursors were systematically studied.X-ray diffraction,thermogravimetric,X-ray photoelectron spectroscopy were used to reveal the phase evolution behavior,thermal stability of the precursor and the valence state change of transition metal elements during high temperature treatment.
