Abstract

Abstract: The precursors were prepared from lithium hydroxide, manganese acetate and citric acid by the method of low heating solid state reaction with the molar ratio of Li⁺ to Mn ²⁺ as 1∶2. The composition, structure, reaction mechanism and thermo decomposing process of the precursor were studied by using elemental analysis, IR spectrum, MS spectrum and TG/DTA analysis. The results show that the composition of precursor was fitted as LiMn₂L(Ac)₂, in which L represents citric acid radical and Ac was acetic acid radical. Spinel LiMn₂O₄began to form only at 350 ℃ for 4 h.

Key words: Low heating solid state reaction, Precursor, Spinel LiMn₂O₄
