Electrochemical Performance of Li1.2Fe0.052Ni0.078Co0.13Mn0.54O2/C as Cathode Materials
摘要
Abstract
The Li1.2Fe0.052Ni0.078Co0.13Mn0.54O2 cathode material with MnO2 as template shows excellent electrochemical performance by carbon surface treatment and moderate iron ion replacement of nickel ions.XRD analysis shows that the obtained materials have a layered α-NaFeO2 structure.Meanwhile,the transmission electron microscopy confirms that a clear boundary can be seen due to the carbon surface treatment.The sample delivers a discharge capacity of 210(mA · h/g) at 0.1 C rate and the capacity retention rate is about 86 % after 50 cycles between 2.5 and 4.8 V.关键词
