高温固相法合成水系富锂锰基Li2Mn1-xCoxO3
Synthesizing aqueous lithium-rich manganese-based Li2Mn1-xCoxO3 by high-temperature solid-phase method
摘要
Abstract
Lithium-rich manganese-based Li2Mn1-xCoxO3 cathode material was synthesized by high-temperature solid-phase method.The phase analysis of materials were measured by SEM and XRD technique,the electrochemical performance were measured by cyclic voltammetry and galvanostatic charge-discharge (0.5 mA/cm2,1.00-2.05 V) tests.The incorporation of metallic cobalt did not alter the basic structure of the material.When the cobalt content x was 0,0.1,0.5 and 0.9,the initial specific discharge capacity was 66.9 mAh/g,375.8 mAh/g,291.2 mAh/g and 331.5 mAh/g,respectively.The optimal electrochemical performance was shown when the cobalt content was 0.1 (x =0.1),the specific capacity could be stayed around 380 mAh/g with the Coulombic efficiency above 90％.关键词
