Precursor Inhomogeneities Influence the Properties of Multimetal Oxides as Shown for LiNi_0.5Mn_1.5O₄ Derived from Hydrothermally Synthesized Precursors.

ABSTRACT: Co-precipitation is an attractive means for synthesizing mixed metal oxides, a material class with a wide range of application prospects. Often soluble metal salts are precipitated as metal hydroxides or -carbonates, which subsequently are converted to the corresponding oxide(s) upon thermal treatment. The thermal treatment step is used to induce compositional homogeneity on the atomic level. In order to shed some more light on this effect, detailed analyses of a mixed Li-Ni-Mn-oxide with the target composition LiNi_0.5Mn_1.5O₄ (LNMO), which is a promising cathode material for rechargeable Li-ion batteries are performed. The first synthesis step is the precipitation of a Ni-Mn-carbonate, which is subsequently thermally lithiated and transformed into an oxide.
