Effect of Synthesis Methods on the Electrochemical Performance of Lithium-Rich Manganese-Based Cathode Material Li1.2Mn0.54Ni0.13Co0.13O2 AITranslate
Abstract AITranslate
Lithium-rich manganese-based cathode material Li1.2Mn0.54Ni0.13Co0.13O2was prepared by co-precipitation,sol-gel,and solid phase methods,and the phase composition and microstructure of the synthesized material were characterized by XRD,SEM,EDS,etc.The electrochemical performance of the CR2032 button type half cell assembled from the synthesized material was tested using a battery testing system.The results indicate that lithium-rich manganese-based cathode materials with a layered structure have been successfully synthesized by the three synthesis methods.Among them,the sample prepared by co-precipitation method exhibits the lowest degree of cation mixing,and has uniform elemental distribution and particle size,clear grain boundary edges,and no obvious agglomeration.In terms of electrochemical performance,the first cycle discharge specific capacity of the sample synthesized by co-precipitation method at a rate of 0.1 C reaches the highest within the voltage range of 2.0~4.8 V.Moreover,after 100 cycles,the prepared sample still maintains a discharge specific capacity of 195.8 mA·h/g,with a capacity retention rate of 87.3%.Comparatively,the samples prepared by sol-gel method and solid phase method has lower capacity retention rates of only 84.5%and 83.8%,respectively.And compared with the samples prepared by sol-gel method and solid phase method,the co-precipitation method can effectively improve the Li+transport efficiency of Li1.2Mn0.54Ni0.13Co0.13O2cathode material,thereby improving the rate performance of the sample.
