Abstract： Using urea as a complexing agent,spinel LiMxMn2-xO4(M=Li,Na,Tl),as homogeneous Li-M-Mn precursors,was prepared with the hydro-thermal reaction of lithium hydroxide,manganese acetate and so on,by a modified solid-state method.These precursors were calcined at various temperatures between 600 ℃-700 ℃ for 4 hours to obtain the final products.The electrochemical properties and other features of the final products were carefully investegated.It was found that the closer ionic radius of the dopant M was to Mn3+,the more stable LiMxMn2-xO4 was.
