Preparation of High-performance Lithium-rich Manganese-based Cathode Materials by Electrospinning AITranslate
Abstract AITranslate
The lithium-rich manganese-based cathode material of Li1.2[Mn0.54Ni0.13Co0.13]O2 was prepared by electrospinning in order to overcome the shortcomings of low first-cycle efficiency and poor rate performance of lithium-rich manganese-based materials.The experimental results show that the nanofibers prepared by electrospinning have three-dimensional structure and larger specific surface area,which can improve the reactivity and reduce the conduction impedance of lithium ions,thus improving the rate performance and discharge capacity of the materials.At 5 C rate,the discharge specific capacity of the spinning fibers is 175 mA·h/g,while that of the precipitated particles is only 154 mA·h/g.In addition,the first-cycle efficiency is improved from 72.87% to 81.93%,and discharge capacity is also improved.Thus Li-rich manganese-based materials prepared by electrospinning have better performance.
