Improving cycling performance of Li1.2Ni0.13Co0.13Mn0.54O2 by optimizing the precipitant
通过优化沉淀物,提高Li1.2Ni0.13Co0 13Mn0.54O2的循环性能
摘要:Li1.2Ni0.13Co0.13Mn0.54O2 was synthesized with different precipitants and compared in the study. The material synthesized with precipitant of Na2CO3 delivered the highest initial discharge capacity of 307.1 mAh g−1. However, the cycling performance and rate capability of it were not as good as the materials synthesis by the mixed precipitant of Na2CO3/NH4HCO3. The material synthesized with the mixture of Na2CO3/NH4HCO3 performed the highest discharge capacity retention rate of 82.8 % after 50 cycles at 1.0 C. While the materials synthesized by Na2CO3 as precipitant was only 71.6 %. It was shown that different precipitants had certain effects on the electrochemical performance of the materials and provided a viewpoint for the selection of precipitant in the process of using co-precipitation methods.
