高容量富锂层状材料Li2MnO3·2 LiNi0.5Mn0.5O2的制备与表征
Fabrication and characterization of lithium-rich layered cathode material Li2MnO3·2 LiNi0.5Mn0.5O2 with high capacity
摘要
Abstract
The lithium-rich layered cathode material Li2MnO3·2 LiNi0.5Mn0.5O2 was fabricated by co-precipitation method. The structure and electrochemical properties of the material were examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), cyclic voltammetry and galvanostatic charging and discharging test. The results show that the material has high capacity and good cycle performance. The first discharge special capacity is 187.2 mAh/g;the first and second cycle coulombic efficiency are respectively 74.3%and 97.6%. After 30 cycles, the discharge special capacity stil remains 156.8 mAh/g, which is 83.7%of that of the first cycle.关键词
