Abstract

Lithium manganese oxide nanorods were prepared from manganese dioxide nanorods precursor. The structure and morphology were confirmed by X-ray diffraction (XRD) and transmission electron microscope (TEM). The data of the Rietveld refinement indicate that the nanorods preferentially grow along the [111] direction. After charge–discharge test at 1.0 mA cm−2 in 3.0–4.4 V, the nanorods LiMn2O4 showed the 134.5 mAh g−1 initial discharge capacity and only lost 1.1% of initial capacity after 30 cycles, which is better than that of bulk particles LiMn2O4 prepared by traditional solid-state reaction method. This effective and simple route to synthesis nanorods LiMn2O4 from one-dimensional (1D) precursor could also be extended to prepare 1D other nanomaterials with special electrochemical properties.
