Research on Structure Control and Performance of High Energy Density Lithium-rich Manganese-based Cathode Materials AITranslate
Abstract AITranslate
The lithium-rich manganese-based oxide(LMO)shows high specific capacity,but it still has some defects,such as large initial irreversible capacity loss,poor dynamic performance and voltage decline.In this paper,the structure of Li1.2Ni0.13Co0.13Mn0.54O2 cathode material was designed and optimized.The transfer of lattice oxygen in charge-discharge cycle is limited by doping Br- to substitute O2-.The reversibility of oxygen anion reaction is enhanced by adjusting oxygen vacancy in LMO electrode,and the cycle stability of the electrode is also improved.The substitution of the non-equivalent Br- is more likely to pro-duce oxygen vacancy,thereby increasing the conductivity of the material,improving the Li+diffusion kine-tics,and enhancing the rate performance of the material.
