Nmc cathode density powders12/30/2023 ![]() 0.5LiNi0.5Mn 0.5O 2 synthesized by ionic-liquid-assisted hydrothermal method is much lower, which enhances the reaction kinetics.Besides, electrochemical impedance spectroscopy (EIS) results suggest that the charge transfer resistance of 0.5Li 2MnO 3 Electrochemical test results indicate that the materials synthesized by ionic-liquid-assisted hydrothermal method exhibit better rate capability and cyclability. SEM and TEM images indicate that the extent of particle agglomeration of the ionic-liquid-assisted sample is lower compared to the traditional hydrothermal sample. The XRD results show that the sample prepared by ionic-liquid-assisted hydrothermal method exhibits a typical Li-rich Mn-based pure phase and lower cation mixing. The microstructures and electrochemical performance of the prepared cathode materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electrochemical measurements. Well-dispersed Li-rich Mn-based 0.5Li 2MnO 3♰.5LiNi0.5Mn 0.5O 2 nanoparticles with diameter ranging from 50 to 100 nm are synthesized by a hydrothermal method in the presence of N-hexyl pyridinium tetrafluoroborate ionic liquid (). 3School of Chemistry and Chemical Engineering, Jishou University, Jishou, China.2College of Biology and Environmental Sciences, Jishou University, Jishou, China.1School of Physics and Mechanical and Electrical Engineering, Jishou University, Jishou, China.Yanhong Xiang 1 Youliang Jiang 1 Saiqiu Liu 1 Jianhua Wu 1 Zhixiong Liu 1 Ling Zhu 1 Lizhi Xiong 2 Zeqiang He 2 Xianwen Wu 3 * ![]()
