摘要：
Ternary oxides of Li-Fe-Mn-O system with overstoichiometric spinel structure Li1+xMn1-yFeyO4, have been synthesized. The effect of composition and synthesis temperature on the electrochemical performance of the oxides as a material of positive electrodes of Li-ion batteries has been studied. The optimal temperature of synthesis was found to be 850 degreesC for the composition Li1.2Mn1.6Fe0.4O4. This oxide shows good reversibility at acceptable level of capacity near 105 mAh/g.
