Nanoscale MnO mildly expanded graphite (MnO/MEG) composites were synthesized by a facile hydrothermal method combined with a subsequent self-reduction process using MEG as the raw material. The physicochemical and electrochemical properties of this novel MnO/MEG composite were characterized by X-ray diffraction, scanning electron microscopy, galvanostatic charge/discharge tests, cyclic voltammetry, and electrochemical impedance spectroscopy measurements. MnO/MEG exhibits excellent electrochemical performance for which the reversible capacity is as high as 931 mAh g(-1) at 0.3 C after 450 cycles, which can be attributed to nanoscale MnO on MEG and self-developed graphene during the charge/discharge process.
