Abstract

Abstract:

Lithium ion battery cathode material LiNi_0.8Co_0.15Al_0.05O₂ was prepared by Sol-Gel, respectively, using water, ethanol, ethylene glycol, glycerol as a solvents. Through TG / DSC analysis of the thermodynamic properties, the sintered condition of the sample was selected as pre-treatment at 550℃for 6 h and then ??sintering at 750℃ for 24 h. XRD patterns show that the 018/110 peak of the samples prepared by organic solvent is splitted obviously, but the peak shifts to a small angle, which indicates that the lattice spacing increases. SEM results show that the average particle size of the samples prepared by organic solvent is 0.4 μm, which is smaller than that of the sample (0.5 μm) prepared by using water. Some of the single crystals present in the sample prepared by using ethanol and ethylene glycol as solvent. The electrochemical performance test results show that the charge-discharge performance of samples prepared in the organic solvent is lower than that of the sample prepared in the water. However, the initial discharge capacity (197.33 mAh/g) of the samples prepared using ethanol as a solvent (200.66 mAh/g) is closed to that of the sample prepared by using water as solvent, and cycle performance has greatly improved at 1C rate. After 50 cycles at 1C rate, the capacity retention rate of the sample prepared by using water is increased from 87.1% to 94.4% as compared with the sample prepared by using ethanol. The presence of large crystal particle is beneficial to improve the cycle performance of the NCA material.

Key words: ethanol, Sol-Gel, organic solvent, single crystal
