A facile and simple method to prepare tube‐like nitrogen‐doped graphene (NG)/manganese oxide (Mn 3 O 4 ) composite is introduced. The transmission electron microscopy patterns show that the Mn 3 O 4 nanotubes were uniformly dispersed on the surface of the NGs. The composite was further investigated by Raman spectroscopy, X‐ray diffraction and X‐ray photoelectron spectroscopy. The electrochemical properties of NG/Mn 3 O 4 composites were tested by cyclic voltammetry curves and galvanostatic charge–discharge curves. The results of the electrochemical measurement show the high capacitance and good long‐term stability of NG/Mn 3 O 4 composites.
