Abstract
In this article, zinc-doped sodium manganese oxide (NZMC) was synthesized by a conventional solid-state reaction method. Structure and morphology of the NZMC material were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS). The results show that Zn was successfully doped into the sodium manganese-based oxide (NMC) material. The NZMC material was utilized as a cathode material in CR2032-type coin cells for testing its electrochemical characteristics. The NZMC material had a superior initial discharge capacity of 155 mAh.g-1 between 1.5-4 V at a current density of 0.1 C. The capacity remained at 100 mAh.g-1 after 50 cycles. The results suggest that the NZMC material is a promissing cathode for sodium-ion batteries.
