熔盐法制备梯度型LiNixCoyMn1-x-yO2电极材料的研究
Study on the Concentration-gradient LiNixCoyMn1-x-yO2Electrode Material Prepared in the Molten Salt Method
摘要
Abstract
The layered cathode material LiNi1-x-u, CoxMnyO2 was prepared at different temperatures in the molten salt method. Experiments were carried out to test the charge and discharge properties of the material. The XRD and SEM experiments show that the prepared material has a typical a-NaFeO2 layered structure with the particles diameter range from 200nm to 400 nm. The capacity of the prepared material at 800℃is 166. 8mAh/g with a retention of 99% in the first charge-discharge cycle, tested within the voltage cut off limits of 2. 75 and 4. 5 V. Besides, the results show that the material demonstrates a good rate capability.关键词
