Electrochemical Performance of LiMn2O4 Synthesized from Precursor Mn3O4

Abstract

Abstract: A positive active material of spinel LiMn₂O₄ for lithium-ion batteries was synthesized through a modified solid phase reaction. In this process, LiOH and
precursor Mn₃O₄ obtained from controlled crystallization were mixed togather and incinerated to prepare spinel LiMn₂O₄. Structure and electrochemical
properties of the spinel LiMn₂O₄ were studied. The results of XRD and SEM prove that the material prepared through above method is a pure phase of spinel
LiMn₂O₄ and the sizes of the crystallites are uniform. Electrochemical property tests show that the spinel LiMn₂O₄ has excellent eletrochemical

Key words: lithium-ion battery, spinel LiMn₂O₄, controlled crystallization, Mn₃O₄
