Sodium Manganese Oxide (NaxMnO2) has attracted much attention as cathode materials for alkaline ion battery due to the ability of fast charge and discharge ion Na+, in particular in nanoscale. We report on the synthesis of NaxMnO2 nanowires via hydrothermal synthesis route from Mn2O3 and NaOH solution. The morphological observation indicates that the obtained Na0.44MnO2 nanowires with diameters of about 20-30 nm, length up to several micrometers were formed by this process. The electrochemical properties of fabricated materials were investigated by means of cyclic voltammetry technique and show that Sodium Manganese Oxide (NaxMnO2) is a promising material in the field of research and fabrication alkaline ion battery.

Fe2O3@C material was prepared by one-step hydrothermal method for use as a negative electrode in an iron-air battery. The structure of Fe2O3@C was determined by X-ray diffraction (XRD) measurement while their morphology was observed by scanning electron microscopy (SEM). The electrochemical properties of the Fe2O3@C electrode in alkaline solution were investigated using cyclic voltammetry (CV) measurement. The results showed that Fe2O3@C material with α-Fe2O3 structure and amorphous carbon were successfully synthesized by one-step hydrothermal method. CV measurements indicate that the redox reaction rate of the Fe2O3@C electrode is higher than that of the Fe2O3@AB electrode using commercial Fe2O3 and AB (Acetylene Black Carbon).

The composites of graphene oxide/ Fe2O3-nanotubes (GO/ Fe2O3-NTs) have been fabricated through a facile one-step hydrothermal method. Fe2O3-NTs crystallines were homogeneously distributed on GO, which have been confirmed by transmission electron microscopy analysis (TEM). The structure, composition and electrochemical properties of GO/ Fe2O3-NTs composites were investigated by means of selective-area electron diffraction (SAED), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Raman spectra, cyclic voltammogram (CV) curves and galvanostatic charge–discharge curves. GO/ Fe2O3-NTs composites exhibit a high specific capacitance of 133.2 Fg-1in 1 M Li2SO4electrolyte. In addition, the GO/ Fe2O3-NTs composites electrode shows good long-term cycle stability (only 9% decrease of the specific capacitance is observed after 1000 charge–discharge cycles).
