Effects of Li and Mg Element Doping on Electrochemical Performance of Manganese-based Layered Oxides AITranslate
Abstract AITranslate
The Li-doped compound Na0.75Li0.25Mn0.75O2 and the Mg-doped compound Na;Mg;Mn;O;were synthesized by solid reaction process.Phase composition and morphology of the obtained materials were characterized by using X-ray diffractometer(XRD) and scanning electron microscope(SEM).Sodium storage performance of the materials was tested by galvanostatic charge-discharge and cycle voltammetry.The experimental results show that both Li-doped and Mg-doped materials present layered morphology and P2 crystal structure.The initial discharge capacity of Na0.75Li0.25Mn0.75O2is 146 mA·h/g, and its capacity retention rate after 50 cycles is 79.4%.The initial discharge capacity of Na0.75Li0.25Mn0.75O2 reaches 158 mA·h/g, and its capacity retention rate after 50 cycles is 64.1%.Doping with Li element can more significantly improve the cycle performance of the materials than doping with Mg element.
