Reaction Milling Synthesis and Electrochemical Performance of Spinel LiMn_2O_4 AITranslate
Abstract AITranslate
Spinel LiMn2O4 was synthesized by reaction milling with KMnO4,MnSO4·H2O and LiOH·H2O as the raw material.The samples were characterized by XRD and SEM from structure and surface morphology.The results show that the sample after reaction milling is composed of LiMn2O4,Li2SO4·H2O and KLiSO4.After washing,the product is spinel LiMn2O4,but the crystallization degree is incomplete.After heating at 800 ℃ for 30 min,the synthesized LiMn2O4 is complete crystal,and its grains are fine and uniform with an average diameter of about 500 nm.And its initial discharge capacities are 115.8,107,105.5,98.2 mA·h/g at these discharge rates of 0.2,0.5,1 and 3 C,respectively,based on electrochemical tests.It is also of an excellent cycle performance with only 3.2% capacity fading degree after 10 cycles.
